A stereodivergent and diastereoselective transition-metal-catalyzed intramolecular hydroamidation of allenes and alkynes furnishing d-vinyl-lactams is reported. Employing a rhodium catalyst allowed for the selective synthesis of the syn-d-lactam. Conversely, a palladium catalyst led to the formation of the antid- lactam in high selectivity. The new method shows high functional group compatibility and assorted synthetic transformations were demonstrated as well as its utility for the enantioselective formal total syntheses of (-)-cermizine C and (-)-senepodine G.

Cobalt(II) complexes (5 mol% Co) bearing phosphine-free N<^>N<^>N pincer ligands efficiently catalyze C-C coupling of secondary and primary alcohols to selectively form alpha-alkylated ketones with a good functional group compatibility using NaOH (20 mol%) as a base at 120 degrees C. The NH group on the N boolean AND N boolean AND N Co(II) precatalyst controls the activity and selectivity. This simple catalytic system is involved in the synthesis of quinolones via the dehydrogenative annulation of 2-aminobenzyl alcohols with secondary alcohols. (C) 2019 Elsevier Ltd.

The chelate assistance strategy was devised to promote a highly regioselective catalytic C-C bond activation reaction of saturated and unsaturated carbonyl compounds. The cationic Ru-H complex 1 was found to be an effective catalyst for mediating the coupling reaction of 1,2-disubstituted indoles with alpha,beta-unsaturated aldehydes and ketones, in which the regioselective C-alpha-C-beta activation of the carbonyl substrates has been achieved in forming the 3-alkylindole products. The analogous coupling reaction of indoles with saturated aldehydes and ketones directly led to the C-alpha- C-beta cleavage of the carbonyl substrates in forming the 3-allcylindole products. The coupling reaction of 1,2-dimethylinole with (E)-3-nonen-2-one and 2-propanol-d(8) showed 20-22% of deuterium incorporation to both alpha- and beta-CH2 of the 3-alkylindole product. The coupling reaction of 1,2-dimethylinole with (E)-3-nonen-2-one exhibited the most significant carbon kinetic isotope effect on the alpha-carbon of the product (C-alpha = 1.046). The Hammett plot constructed from the reaction of 1,2-dimethylinole with a series of para-substituted enones p-X-C6H4CH=CHCOCH3 (X = OMe, Me, H, Cl, CF3) showed a modest promotional effect by an electron-donating group (rho = -0.2 +/- 0.1). Several catalytically relevant Ru-H species were detected by NMR from a stoichiometric reaction mixture of the Ru-H complex 1 with 1,2-dimethylindole and (E)-3-nonen-2-one in CD2Cl2. These results support a mechanism of the catalytic coupling reaction via conjugate addition of indoles to enones followed by the C-C bond activation and hydrogenolysis steps.

Computed Properties of C15H12O. I found the field of Biochemistry & Molecular Biology; Chemistry; Polymer Science very interesting.

Chitosan copper (II) oxide nanocomposite was synthesized, characterized and used to synthesize [1,2,3] triazoles. Nanocomposite was characterized by using FTIR, XRD, FESEM, and EDS techniques, which reflected rough morphology. The powerful catalytic activity of hybrid nanocomposite was utilized to synthesize chalcones (3a-p) in relatively high yields (82%-98%) and multicomponent regio-selective cycloaddition of chalones, aryl halides (4), and sodium azide to afford the expected N-2-aryl[1,2,3]triazoles (5a-h) (80%-95% yield) rather than N-1-aryl(1,2,3]-triazoles (6a-h). The performance of nanomaterial was optimized by several variables. The capability of the nanocomposite was compared with previous work and the nanocomposite was found more efficient, economic and reproducible. The hybrid nanocomposite could be easily isolated form the reaction mixture and recycled four times without any significant loss of its catalytic activity. The reported catalyst is an inexpensive for good yields of the triazoles and may be used at industrial production for the reported compounds. (C) 2019 Published by Elsevier B.V.

Five [PSiP]-pincer iron hydrides1-5, [(2-Ph2PC6H4)(2)HSiFe(H)(PMe3)(2)(1), (2-Ph2PC6H4)(2)MeSiFe(H)(PMe3)(2)(2), (2-Ph2PC6H4)(2)PhSiFe(H)(PMe3)(2)(3), (2-(iPr)(2)PC6H4)(2)HSiFe(H)(PMe3) (4), and (2-(iPr)(2)PC6H4)(2)MeSiFe(H)(PMe3)(2)(5)], were used as catalysts to study the effects of pyridine N-oxide and the electronic properties of [PSiP]-ligands on the catalytic hydrosilylation of carbonyl compounds. It was proved for the first time that this catalytic process could be promoted with pyridine N-oxide as the initiator at 30 degrees C because the addition of pyridineN-oxide is beneficial for the formation of an unsaturated hydrido iron complex, which is the key intermediate in the catalytic mechanism. Complex 4 as the best catalyst shows excellent catalytic performance. Among the five complexes, complex 3 was new and the molecular structure of complex 3 was determined by single crystal X-ray diffraction. A proposed mechanism was discussed.

The complexes (Ir(4tfmpq)(2)mND, Ir(4tfmpq)(2)mmND, and Ir(4tfmpq())2mpND) emit pure red emissions of 626-630 nm with high photoluminescence quantum yields of 85.2-93.4% in CH2Cl2 and better electron mobilities than that of tri(8-hydroxyquinoline)aluminum. By employing three pure red emitters, all the phosphorescent organic light-emitting diodes exhibited superior performances with a maximum external quantum efficiency of 31.48% and the efficiency roll-off is very mild, which are among the best results ever reported for pure red organic light-emitting diodes using Ir(III) complexes.

A straightforward access to tricyclic indoles bearing 3,4-fused seven-membered rings has been established by using 4-aminoindoles as 1,4-bisnucleophiles in three-component reactions. 1H-Azepino[4,3,2-cd]indoles, 4,6-dihydro-1H-azepino[4,3,2-cd]indoles and 1,3,4,6-tetrahydro-5H-azepino[4,3,2-cd]indol-5-ones could thus be synthesized in one pot in moderate to good yields. Beyond opening access to 3,4-fused tricyclic indoles, the use of easily accessible 4-aminoindoles as C,N-1,4-bisnucleophiles also provides a new platform to be used in a diversity-oriented synthesis strategy, fully displaying its benefits of maximizing molecular complexity and reaction diversity.

Chitosan microspheres modified by 2-pyridinecarboxaldehyde were prepared and used in the construction of a heterogeneous catalyst loaded with nano-Cu prepared by a reduction reaction. The chemical structure of the catalyst was investigated by Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and X-ray Photoelectron Spectroscopy (XPS). Under mild conditions, such as no ligand at room temperature, the catalyst was successfully applied to catalyze the borylation of alpha,beta-unsaturated receptors in a water-methanol medium, yielding 17%-100% of the corresponding beta-hydroxy product. Even after repeated use five times, the catalyst still exhibited excellent catalytic activity.

The first total synthesis of a marine natural product, exigurin, has been accomplished in 13 steps starting from (+)-menthone. The key intermediate (-)-10-epi-axisonitrile-3 was prepared by stereoselective intramolecular cyclopropanation followed by a cyclopropane ring opening reaction by the azide anion. The bioinspired Ugi reaction of (-)-10-epi-axisonitrile-3, formaldehyde, sarcosine and methanol successfully constructed the target exigurin in which its terpene and amino acid units were linked through an amide bond.
