The Michael-induced ring closure (MIRC) of amines with 2-bromoalkylidenemalonates has been reinvestigated and the reaction products with primary amines have been identified as (2-iminoethyl)malonates and not 2-aminoalkylidenemalonates as previously reported. The (2-iminoethyl)malonates are formed by ring opening of the intermediate unstable 2-aminocyclopropane-1,1-di-carboxylates (β-ACCs) and were
迈克尔诱导的胺与 2-溴亚烷基丙二酸酯的闭环 (MIRC) 已被重新研究,与伯胺的反应产物已被确定为 (2-亚氨基乙基) 丙二酸酯,而不是先前报道的 2-氨基亚烷基丙二酸酯。(2-亚氨基乙基)丙二酸酯由中间不稳定的 2-氨基环丙烷-1,1-二羧酸盐 (β-ACC) 开环形成,并通过光谱和化学转化进行表征。
