Abstract
The convergent synthesis of a class of enediyne-imides as well as their palladium-catalyzed branching cyclizations, which can be accomplished in two ways leading to a set of polysubstituted furo[2,3-b]pyridines upon using the N-tosyl carboxamide moiety as an N,O-bisnucleophile, are presented.
摘要
呈现了一类烯二炔亚胺的汇聚合成以及它们的钯催化支化环化反应，通过使用 N-对甲苯磺酰基羧酰胺作为 N,O-双亲核试剂，可以以两种方式完成，得到一组多取代的呋喃[2,3-b]吡啶。
