Copper(I) chloride mediated cyclization of optically active 2,3-allenoic acids or 1:1 salts of optically active 2,3-allenoic acids with chiral amines was developed. The reaction of optically active 2,3-allenoic acids in methanol requires only a catalytic amount of copper(I) chloride, while the reaction of the 1:1 salts of optically active 2,3-allenoic acids with chiral amines needs one equivalent of
开发了氯化铜 (I) 介导的旋光 2,3-丙二烯酸或旋光 2,3-丙二烯酸与手性胺的 1:1 盐的环化。光学活性 2,3-烯丙酸在甲醇中的反应只需要催化量的氯化铜 (I),而光学活性 2,3-烯丙酸的 1:1 盐与手性胺的反应需要一当量氯化铜(I),应在二氯甲烷中进行,以确保高效率的手性转移。
