Abstract Synthesis of a series of 1aR,2S,4aS-hexahydropyrrolo[3,4-b]quinolines has been achieved by the intramolecular cyclization reaction of aldimines derived from aromatic amines and (S)-2-(N-(3-methylbut-2-enyl)-N-tosyamino)-3-methylpropanal/(S)-2-(N-(3-methylbut-2-enyl)-N-tosyamino)-3-phenylpropanal in acetonitrile with InCl3 as a catalyst, in excellent yields and in short duration of time, under
摘要 通过芳香胺衍生的醛亚胺与 (S)-2-(N-(3-methylbut-) 分子内环化反应合成了一系列 1aR,2S,4aS-六氢吡咯并[3,4-b]喹啉。 2-烯基)-N-甲苯磺酰氨基)-3-甲基丙醛/(S)-2-(N-(3-甲基丁-2-烯基)-N-甲苯磺酰氨基)-3-苯基丙醛在乙腈中用 InCl3 作为催化剂,在在温和的条件下,产量高,持续时间短。图形概要
