The one-pot three-component reaction of terminal alkynes, aldehydes and secondary amines in the presence of copper(I) bromide/quinap is reported. The reaction scope has been determined and a broad variety of all three components has been used, which afforded the corresponding propargylamines in good to excellent yields and moderate to very good enantioselectivities. The reaction showed a strong positive
报道了在溴化铜(I)/喹啉存在下,末端炔烃,醛和仲胺的一锅三组分反应。已经确定了反应范围,并且使用了所有三种组分的各种,从而以良好至优异的产率和中等至非常好的对映选择性提供了相应的炔丙基胺。该反应显示出强烈的正非线性效应。还已经描述了炔丙胺中间体向生物碱(S)-(+)-con氨酸的转化。
