摘要：

Functionalized chiral carbazolones with α-quaternary carbon centers are formed through the ligand-controlled Pd-catalyzed enantioselective decarboxylative allylic alkylation of carbazolones (see scheme). This catalytic asymmetric reaction was employed as the key step in the total synthesis of aspidospermidine and (+)-kopsihainanineA. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
