A rhodium(I)-catalyzed demethylation-cyclization of o-anisole-substituted ynamides in the synthesis of chiral 2-amido benzofurans.
Org Lett. 2007 Jun 07; 9(12):2361-4.OL

Abstract

A Rh(I)-catalyzed demethylation-cyclization sequence for a direct transformation of o-anisole-substituted ynamides to benzofurans is described here. The Ag salt functions synergistically with Rh(I) for the key demethylation step.
