Highly Substituted Pyrroles by a Gold(I)-Catalyzed Tandem Reaction of 1-(1-Alkynyl)cyclopropyl Oxime Ethers with Nucleophiles
摘要:
A gold(I)-catalyzed tandem reaction of 1-(1-alkynyl) cyclopropyl oxime ethers with nucleophiles under mild conditions has been developed, which provides a facile access to highly substituted pyrroles in moderate to excellent yields.

Gold-catalyzedcascadecyclization and 1,3-difunctionalization of 2-(1-alkyny)-2-alken-1-ones with N,O-acetals are described, leading to the discovery of novel 1,3-oxyaminomethylation and 1,3-aminomethylamination. Typically, by varying the reaction conditions especially the gold catalysts, these two distinct reaction pathways can be controlled in a selective manner. Moreover, tandem cyclization and
