Facile and Selective Synthesis of Propargylic Amines and 1,6-Diynes: One-Pot Three-Component Coupling Reactions of Alkynylsilanes, Aldehydes and Amines by a Cooperative Catalytic System Comprised of CuCl and Cu(OTf)2
摘要:
Described herein is a three-component coupling reaction of alkynylsilanes, aldehydes and amines by a cooperative catalytic system comprised of CuCl and Cu(OTf)(2), leading to the production of a variety of propargyl amine derivatives. This catalytic system was successfully applied to the practical preparation of 1,6-diyne derivatives via twice-performed, domino-type coupling reactions.
