A copper-catalyzed cross-coupling of organotin reagents with imines and acid chlorides is reported. The reaction proceeds efficiently with a range of vinyl-, alkyl-, aryl- and heteroaryl-substituted organostannanes as well as a diverse set of imines of non-enolizable aldehydes. Use of chloroformates also allows for the formation of N-protected α-substituted amines. This chemistry has been applied to
据报道,铜催化的有机锡试剂与亚胺和酰氯的交叉偶联。该反应可与一系列乙烯基,烷基,芳基和杂芳基取代的有机锡烷基酯以及各种各样的不可烯化的醛亚胺有效地进行。使用氯甲酸酯还可以形成N-保护的α-取代的胺。该化学方法已用于通过环亚胺的活化来合成异喹啉生物碱衍生物。
