Tandem Gold(III)-Catalyzed Amination-Intramolecular Hydroamination Reactions of 1-En-4-yn-3-ols with Sulfonamides: Efficient Approach to Highly Substituted Pyrroles
A simple, convenient and efficient synthetic approach to highlysubstitutedpyrroles has been developed by utilizing a gold(III)-catalyzedtandemamination-intramolecularhydroaminationreaction. The first examples of gold-catalyzed, selective amination of 1-en-4-yn-3-ols have also been disclosed.
