- A Novel Palladium-Mediated Cascade Reaction Triggered by Strain Release of the Cyclobutane System. A New General Route to Benzo- and Naphthohydrindans
-
A novel palladium-mediated cascade reaction was reported.By this procedure, the olefinic cyclobutanols 17, 24, and 31; 41; 37; and 45 afforded the benzo- and naphthohydrindans (46-49, 50-53, 54-57, and 58-61) respectively in one operation in the ratios depending on the mediators and solvents employed.This provides a novel and efficient synthesis of biologically important A-nor and C11-alkylated steroids.
