Abstract

Solid-phase synthesis of fused [2, 1-b] quinazolinone alkaloids has been developed for the preparation of vasicinone and deoxyvasicinone by two approaches. The derivative of polymer-supported p-nitrophenyl carbonate was attached to anthranilic acid and then coupled with various bromo-lactams. This resin-linked bromo intermediate upon acetylation, hydrolysis and resin cleavage gave the cyclized [2, 1-b] quinazolinones (vasicinone). ...
