Direct construction of carbazoles from 2-methyl-indole-3-carbaldehydes and enals
作者:Dehai Liu、Jie Huang、Zhenqian Fu、Wei Huang
DOI:10.1039/c9gc00064j
日期:——
The direct and rapid construction of carbazoles was achieved via the reaction of 2-methyl-indole-3-carbaldehydes with enals promoted by LiCl/DBU in a single operation. This mild and green reaction proceeds through a [4 + 2] cycloaddition/dehydration/oxidative aromatization cascade to generate carbazoles in good to excellent yields. The reaction features mild reaction conditions, a broad substrate scope
Structural and mechanistic studies of the base-induced Sommelet–Hauser rearrangement of N-α-branched benzylic azetidine-2-carboxylic acid-derived ammonium salts

日期:——
The base-induced Sommelet–Hauser rearrangement of N-α-branched benzylic azetidine-2-carboxylic acid ester-derived ammonium salts to obtain α-arylazetidine-2-carboxylic acid esters was investigated. The substrates, two diastereomeric salts (1S,2S,1’S)- and (1R,2R,1’S)-2, showed different reactivities. The rearrangement of (1S,2S,1’S)-2a proceeded with a perfect N-to-C chirality transfer to provide (R)-3a

trifluoromethanesulfonate as catalysts in the presence of triphenylphosphine. This synthesis process involves nitrene formation, C–H bond insertion, C═C bond rearrangement, and C–N bond formation cascade reactions via copper- and molybdenum-catalyzed mediation. The method features a wide substrate scope and a moderate to high yield (up to 90%), exhibiting the possibility for practical applications
提出了一种在三苯基膦存在下,以乙酰丙酮钼和三氟甲磺酸铜 (II) 为催化剂,从邻硝基苯甲酸N-烯丙基酰胺合成 1,4-苯二氮卓-5-酮的新型有效方法。该合成过程包括氮烯形成、C-H 键插入、C=C 键重排以及通过铜和钼催化介导的 C-N 键形成级联反应。该方法具有广泛的底物范围和中高产率(高达 90%),具有实际应用的可能性。
