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.

A panel of six new arene Ru (II)-NHC complexes 2a-f, (NHC = 1,3-diethyl-(5,6-dimethyl)benzimidazolin-2-ylidene 1a, 1,3-dicyclohexylmethyl-(5,6-dimethyl)benzimidazolin-2-ylidene 1b and 1,3-dibenzyl-(5,6-dimethyl)benzimidazolin-2-ylidene 1c) were synthesized from the transmetallation reaction of Ag-NHC with [(eta(6)-arene)RuCl2](2) and characterized. 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.

The regioselective hydroboration of aliphatic internal alkenes remains a great challenge. Reported herein is an iridium-catalyzed hydroboration of aliphatic internal alkenes, providing distal-borylated products in good to excellent yields with high regioselectivity (up to 99:1). We also demonstrate that the C-B bond of the distal-borylated product can be readily converted into other functional groups. DFT calculations indicate that the reaction proceeds through an unexpected Ir-III/Ir-V cycle.

Terpenoid derivatives, which contain a preserved carane system in their structure, exhibit a broad spectrum of biological activities. Among them, we can distinguish insecticides, structures with pharmacological application etc. In the presented paper, the substrate – (-)-cis-caran-trans-4-ol was transformed using the reactions of typical organic synthesis to obtain novel derivatives. Most importantly, bromolactone ((-)-(1R,4R,6S)-2′-(bromomethyl)-4,7,7-trimethylspiro[bicyclo[4.1.0]heptan-3,3′-furan]-5′(4’H)-one) with the preserved carane system was synthesized. This bromolactone was tested for antifeedant activity against the lesser mealworm, Alphitobius diaperinus Panzer, and peach potato aphid (Myzus persicae). In addition, its moderate antibacterial activity was observed against the Bacillus subtilis strain (with Minimal Inhibitory Concentration of 200 mu g/mL).

Hsp90, as a key molecular chaperone, plays an important role in modulating the activity of many cell signaling proteins and is an attractive target for anticancer therapeutics. Herein, we report the discovery of N-pyridoyl-Delta(2)-pyrazoline analogs as novel Hsp90 inhibitors by integrated approaches of drug design, organic synthesis, cell biology, and qualitative proteomic analysis. Novel chemical compounds were designed and optimized in the adenosine triphosphate-binding site of Hsp90; lead optimized compounds were found to have significant interactions with Asp93 and other amino acids crucial for Hsp90 inhibition. The designed compounds were synthesized by a two-step procedure; different aromatic aldehydes were reacted with various acetophenones to form substituted 1,3-diphenyl-prop-2-enones (Ic-Io), which upon reaction with isonicotinic acid hydrazide in the presence of glacial acetic acid form N-pyridoyl-Delta(2)-pyrazoline compounds (PY1-PY13). Compounds PY3, PY2, and PY1 were identified as potential leads amongst the series, with promising anticancer activity against human breast cancer and melanoma cells, and the ability to inhibit Hsp90 similar to radicicol by drug-affinity responsive target stability proteomic analysis in a whole-cell assay.
