Abstract

Herein we report the efficient and selective two-step synthesis of various 3-silyl-2-amidoindenones from easily accessible ynamides. This sequence involves a regio- and stereo-selective silylcyanation followed by a Houben–Hoesch type cyclization. Thanks to post-transformations, various 3-substituted 2-amidoindenones could be obtained.
