摘要

We have developed a gold-catalyzed intramolecular cyclization of variously Substituted acetylenic amines under mild conditions, which yields pyrrolopyridines and 2-substituted indoles, quantitatively. The cycloisomerization of acetylenic amines was achieved with AuCl(3) as catalyst Without the use of base, acid or N-protecting group.
