Syntheses of vinylindoles via a Brønsted acid catalyzed highly regio- and stereoselective cis-hydroarylation of ynamides
摘要:
A highly regio- and stereoselective Bronsted acid-catalyzed coupling of ynamides and indoles is described. This process is the equivalent of hydroarylation of ynamides and leads to the efficient syntheses of vinylindoles. Diels-Alder reaction between the vinylindoles and DMAD afforded carbazole derivatives in good yields. (c) 2005 Elsevier Ltd. All rights reserved.
