Abstract
Abietic acid and its derivatives have broadly been used in fine chemicals and are renewable resources. Its inherent chiral rigid tricyclic phenanthrene skeleton is unique. Its utilities in asymmetric catalysis remain to be explored. A series new amide-type chiral quaternary ammoniums bearing dehydroabietylamine were designed, and prepared by two convenient steps. Acylation of dehydroabietylamine with bromoacetyl chloride afforded amide holding bromoacetyl group in higher yields using triethyl amine as base. Subsequent quaternization reaction gave the desired amide-type chiral quaternary ammoniums. The new chiral quaternary ammoniums can be used as phase-transfer catalyst (PTC) for the transition metal-catalysed alkynylation of isatin derivatives.

Abstract
A conformationally restricted perhydro-1,3-benzoxazine derived from (-)-8-aminomenthol behaves as a good chiral ligand in the dimethylzinc-mediated enantioselective monoaddition of aromatic and aliphatic terminal alkynes to 1,2-diketones. The corresponding α-hydroxyketones were obtained in good yields with high enantioselectivities starting from both aromatic and aliphatic 1,2-diketones. The alkynylation of unsymmetrical 1,2-diketones with electronically different substituents also proceeds with high regio- and enantioselectivity. This reaction provides a practical method to synthesize ketones bearing a chiral tertiary propargylic alcohol.

Abstract
In this report, we describe a simple visible light-triggered Barbier-type reaction by employing acetenyl ketones with benzyl trifluoroborates. Through a radical-radical cross-coupling process, this photocatalytic protocol furnished a wide range of tertiary propargyl alcohols. Mechanistic investigation indicated that proton-coupled electron transfer (PCET) might be involved in the photochemical transformations.

[PMID: 31458884 PMCID: PMC6644373 DOI: 10.1021/acsomega.8b01047] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/18/2018] [Accepted: 06/15/2018] [Indexed: 05/08/2023]
Abstract
Zinc(II)-catalyzed (10 mol % ZnCl2) coupling of acyl hydrazides and dialkylcyanamides in ethanol leads to 3-dialkylamino-1,2,4-triazoles (76-99%; 17 examples). This reaction represents a novel, straightforward, and high-yielding approach to practically important 3-NR2-1,2,4-triazoles, which utilizes commercially available and/or easily generated substrates. Seventeen new 3-NR2-1,2,4-triazoles were characterized by HRESI+-MS and IR, 1H, and 13C{1H} NMR spectroscopies and five species additionally by single-crystal X-ray diffraction (XRD). The ZnII-catalyzed reaction proceeds via initial generation of the [Zn{RC(=O)NHNH2}3](ZnCl4) complexes (exemplified by isolation of the complex with R = Ph, 76%; characterized by HRESI+-MS, IR, CP-MAS TOSS 13C{1H} NMR, and XRD). Electronic effects of substituents at the acyl hydrazide moiety do not significantly affect the reaction rate and the yield of the target triazoles, whereas the steric hindrances reduce the reaction rate without affecting the yield of the heterocycles.
