Saa, Carlos,Guitian, Enrique,Castedo, Luis,Suau, Rafael,Saa, Jose Manuel

, p. 2781 - 2784 (1986)

13-Alkyl and 13-aryl substituted 8-oxoprotoberberines were obtained by interamolecular benzyne cycloaddition of isoquinolinopyrrolinediones with arynes.This convergent and highly regioselective reaction has been applied to the synthesis of (+/-)-corydalin
