Abstract

Raymond L. Funk,* Gary L. Bolton Department of Chemistry University of Nebraska-Lincoln Lincoln, Nebraska 68588- 0304 Received August 28, 1984 ... Directed Ortho Metalation Induced Epoxy Cyclialkylation. Regiospecific 5-Exo-Tet and 6-Exo-Tet Routes to Benzofurans and Benzopyrans ... Summary: Metalation of epoxybenzamides 7a-d, 11,13, 15 occurs by regiospecific 5-exo-tet and 6-exo-tet ring- closure modes and leads to benzofuran and benzopyran derivatives ...
