Indolizidines Mannich cyclization

An oxidative Mannich cyclization methodology allowed the synthesis of indolizidine skeletons. The oxidation of the a-silylamide 140 with ceric ammonium nitrate (CAN) formed in situ an iV-acylaminium cation, which cyclized to afford the bicyclic compound 141 (Scheme 35) <1998JOC841>. [Pg.380]
