wide variety of tertiary propargylic amines were synthesized in good to excellent yields from easily accessible starting materials. This three-component assembling was also effective when using potassium phthalimide or di-tert-butyliminodicarbonate instead of secondary amines. Consequently, it provides a quick entry to N-protected propargylic amines suitable intermediates for the synthesis of primary and
描述了一种高效的钯铜催化的炔丙基卤化物,芳基或杂芳基卤化物和仲胺的三组分组装。从易于获得的起始原料中,以高至优异的产率合成了多种叔炔丙基胺。当使用邻苯二甲酰亚胺钾或叔丁基亚氨基二碳酸酯代替仲胺时,这种三组分组装也是有效的。因此,它可以快速进入N-保护的炔丙基胺是合成伯和仲炔丙基胺的合适的中间体。以类似的方式,有效地获得了包括炔丙基酰胺,氨基甲酸酯和磺酰胺衍生物的相关化合物。该催化多米诺三组分工艺已成功地用于构建具有生物学意义的功能化2-(氨基甲基)苯并[ b ]呋喃或吲哚衍生物。
