A simple, mild, and efficient catalytic aminothiolation of terminal alkynes for the synthesis of both 2- and 3-substituted thiazolo[3,2-a]benzimidazoles is established upon catalysis with copper(I), in which complementary regioselectivities could be achieved by using sterically different phenanthroline-based ligands.
通过铜(I)催化建立了一种简单,温和且有效的末端炔烃催化氨基巯基化反应,用于合成2-和3-取代的噻唑并[3,2- a ]苯并咪唑,其中可通过以下方法实现互补的区域选择性:使用空间不同的基于菲咯啉的配体。
