or terminal propargylamines and chalcones via A3-coupling reaction of aldehydes, amines, and alkynes catalyzed by an easily available catalyst Ag2CO3 under solvent-free condition. The reaction proceeded smoothly to deliver various products in good-to-excellent yields with good functional group tolerance. Gram-scale preparation, bioactive molecule synthesis and asymmetric substrates have been demonstrated
几个简单,快速和实用的协议已被开发来合成内部或末端炔丙胺和查耳酮通过甲3 -耦合醛,胺的反应,和炔由容易获得的催化剂催化的Ag 2 CO 3无溶剂条件下进行。反应进行得很顺利,以良好的收率和良好的官能团耐受性提供了各种产品。已经证明了克级制备,生物活性分子合成和不对称底物。此外,已经提出了合成不同产物的合理机制。
