Copper-catalyzed aminothiolation of terminal alkynes with tunable regioselectivity

Article abstract of DOI:10.1039/c8cc09122f

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.
