Bacterial lipopolysaccharides (LPS) are important bio-medical structures, playing a major role in the interaction with human immune systems. Their core regions, containing multiple units ofl-glycero-d-mannoheptoses (l,d-heptose), are highly conserved structurally (withO3 andO7 glycosidic bonds), making them an epitope of high interest for the potential development of new antibiotics and vaccines. Research in this field has always been restricted by the limited availability of the parentl,d-heptose as well as its biochemical epimeric precursord-glycero-d-mannoheptose (d,d-heptose). This problem of availability has recently been solved by us, through a rapid and efficient practical synthesis ofl,d-manno-heptose peracetate demonstrated at scale. Herein we report an optimized, technically simple and versatile synthetic strategy for the differentiation of both thel-glyceroandd-glycero-d-mannoheptose scaffolds. Our approach is based on an orthoester methodology for the differentiation of all three positions of the sugar core using aO6,O7-tetraisopropyl disiloxyl (TIPDS) protecting group for the exocyclic positions. Furthermore, the regioselective opening toward 7-OH acceptors (6O-FTIPDS ethers) differentiates the exocyclic diol which has been demonstrated with a broader set of substrates and for bothmanno-heptoses for the first time.

A series of spiro-[indoline-3,3 ‘-pyrrolizin/pyrrolidin]-2-ones, 4, 5 and 6 were synthesized in a sequential manner from Cu-TEMPO catalyzed dehydrogenation of alkylated ketones, 1 followed by 1,3-dipolar cycloaddition of azomethine ylides via decarboxylative condensation of isatin, 2 and l-proline/sarcosine, 3 in high regioselectivities and yields. The detailed mechanistic studies were performed to identify the reaction intermediates, which revealed that the reaction proceeds via dehydrogenative cycloaddition. Additionally, the regio and stereochemistry of the synthesized derivatives were affirmed by 2D NMR spectroscopic studies. The synthesized derivatives were explored further with molecular docking, in vitro antioxidant, and anti-diabetic activities.

A new series of 1,2,3-triazole tethered chalcone acetamide derivatives (7a-c & 8a-r) have been synthesized in excellent yields and their structures were determined by analytical and spectral (FT-IR, H-1 NMR, C-13 NMR HRMS) studies. The newly synthesized derivatives were evaluated for their cytotoxic activity against four human cancer cell lines, such as HeLa (Human cervical cancer), A549 (Human alveolar adenocarcinoma), MCF-7 (Human breast adenocarcinoma) and SKNSH (Human brain cancer). Among them, compound 7c exhibited good anti-proliferation activity with HeLa (IC50 7.41 + 0.8 mu M), SKNSH (IC50 8.68 + 1.1 mu M), MCF-7 (IC50 9.76 + 1.3 mu M) and MDA-MB-231, while compounds 7a and 7b showed promising anti-proliferation against above four human cancer cell lines with IC50 7.95-11.62 mu M, respectively, compared with the standard drug Doxorubicin. We explored the probable key active site and binding mode interactions in HDAC8 (PDB ID:3SFH) and EHMT2 (PDB ID:3K5K) proteins. The docking results are complementary to the experimental observations.

The cyclic five-membered frustrated phosphane/borane Lewis pairs 11 a, b featuring the bulky octaethylhydrindacenyl- (Eind) substituent or its mono-bromo derivative ((Br)Eind) at phosphorus are monomeric at room temperature. The reactive frustrated Lewis pairs (FLPs) cleave dihydrogen. The cyclic FLP 11 b ((Br)Eind) undergoes 1,2-P/B addition to ethylene to give the zwitterionic heteronorbornane derivative 14 b. It reacts similarly with the carbon-carbon double bond of norbornene. With a variety of organic pi-reagents, the cyclic FLP 11 b often undergoes reaction sequences reminiscent of the Alder-Rickert reaction: the cycloaddition reaction is followed by rapid cycloreversion to form new five-membered heterocyclic FLP products with extrusion of ethene. Reactions of 11 b with benzaldehyde or with acetylenes follow this reaction pattern.

Direct selective desaturation of carbonyl compounds to synthesize alpha,beta-unsaturated carbonyl compounds represents an environmentally benign alternative to classical stepwise procedures. In this study, we designed an ideal CeO2-supported Pd(II)-on-Au nanoparticle catalyst (Pd/Au/CeO2) and successfully achieved heterogeneously catalyzed selective desaturation of cyclohexanones to cyclohexenones using O-2 in air as the oxidant. Besides cyclohexenones, various bioactive enones can also be synthesized from the corresponding saturated ketones under open air conditions in the presence of Pd/Au/CeO2. Preliminary mechanistic studies revealed that alpha-C-H bond cleavage in the substrates is the turnoverlimiting step of this desaturation reaction.

The catalytic asymmetric epoxidation of alpha,beta-unsaturated ketones by tert-butylhydroperoxide (TBHP) has been well established using rare-earth metal amides RE[N(SiMe3)(2)](3) (RE = La(1), Nd(2), Sm(3), Y(4), Yb(5)) with chiral TADDOL ligands. It was found that the combination of Yb[N(SiMe3)(2)](3) and chiral TADDOL ligand H2L2 ((4S,5S)-2,2-dimethyl-alpha,alpha,alpha ‘,alpha ‘-tetra-3,5-bis(trifluormethylphenyl)-1,3-dioxolane-4,5-dimethanol) in a 1 : 1 molar ratio was the optimal choice, which provided the desired epoxides in excellent yields (89-99%) and good to high enantioselectivities (57-94% ee), using DBU as an additive. Various substrates were proved to have functional group tolerance. In addition, gram-level experiments and derivatization experiments were also studied.

A dehydrative C- and S-alkylation procedure by nucleophilic substitution of gamma-hydroxysufones with arenes and thiophenols is reported. This study represents an elegant and ecological concept to construct C-C and C-S bonds leading to unsymmetrical 1,1- and 3,3-branched propanes. The gamma-hydroxysufones underwent BF3 center dot OEt2-mediated dehydrative arylation and thiolation at room temperature and elimination at 40 degrees C. The nucleophile attack occurred on the less hindered side of a planar benzylic carbocation to furnish the title compounds with good diastereoselectivity.

The ruthenium (II)-NHC complexes 2a-f were developed as effective catalysts for alpha-alkylation of ketones and synthesis of bioactive quinoline using primary/amino alcohols as coupling partners respectively. The reactions were performed with 0.5 mol% catalyst load in 8 h under aerobic condition and the maximum yield was up to 96%. Besides, the different alkyl wingtips on NHC and arene moieties were studied to differentiate the catalytic robustness of the complexes in the transformations.

A number of diversely functionalized derivatives of a novel [1,3]selenazolo[4,5-d]pyrimidine have been synthesized through heterocyclization of some 2,4,5-trisubstituted-1,3-selenazoles with orthoesters in refluxing acetic acid. The synthetic compounds were evaluated for their antimicrobial activity against a panel of microorganisms including Gram-negative bacteria, Gram-positive bacteria, and pathogenic fungi. The antifungal results revealed that the new selenium-containing heterocycles were as good as or sometimes better than terbinafine and fluconazole. The in vitro anticancer activities of aforementioned heterocyclic compounds were screened against human breast carcinoma MCF-7 and HeLa cervical cancer cells as well as HDF (human dermal fibroblast) normal cells. Antiproliferative results indicated that compounds with piperidine moiety on MCF-7 cells and with morpholine moiety on HeLa cells exhibited well broad-spectrum of anticancer activities with 397, 298 and 235 mu M and 533, 390 and 204 mu M of IC(50)values after 24, 48 and 72 h of treatments, respectively, while they had no significant toxic effects on normal cells.

C3-(Trans-2-arylethenyl)carbonylated chlorophyll derivatives possessing a bacteriochlorin or chlorin pi-system were synthesized by cross-aldol (Claisen-Schmidt) condensation of methyl pyrobacteriopheophorbide-a or 3-acetyl-3-devinyl-pyropheophorbide-a bearing the C3-acetyl group with p-(un)substituted benzaldehydes under basic conditions. The corresponding porphyrin-type chlorophyll derivatives were prepared by the oxidation (17,18-didehydrogenation) of the chlorin-type. Their Qy absorption and fluorescence emission maxima in dichloromethane correlated well with Hammett substituent constants of the p-substituents. Several electron-withdrawing p-substituents suppressed the emission due to photoinduced electron transfer quenching in a molecule. The substitution sensitivities for their maxima and fluorescence quantum yields decreased in the order of bacteriochlorin-, chlorin- and porphyrin-type derivatives.
