New Synthetic Approaches to Cyclopentaphenanthrenes and Their Carcinogenic Derivatives
A new general synthetic approach to cyclopentaphenanthrenes including their carcinogenic 11-methyl (1b) and 17-keto (2d and 2b) derivatives is reported.The simplest example entails alkylation of the bromomagnesium salt of an enamine derivative of cyclo
