Novel Photochemical-Diradical Cyclization Methods for Protoberberine Alkaloid Synthesis. Preparation of (+/-)-Xylopinine and (+/-)-Stylopine

A new synthetic approach to members of the protoberberine alkaloid family based upon a photochemical-diradical cyclization methodology is described.

A FACILE SYNTHESIS OF THE SUBSTITUTED TETRAHYDRONAPHTHALENES BY THE BENZO-PETERSON REACTION

Thermal treatment of the o-hydroxymethylbenzylsilanes with an excess maleic anhydride or 2,3-dichloromaleic anhydride afforded the corresponding substituted tetrahydronaphthalenes stereoselectively in satisfactory yields presumably via the o-quinodimethane intermediates generated by the benzo-Peterson reaction.
