Development of the Vinylogous Pictet–Spengler Cyclization and Total Synthesis of (±)-Lundurine A

Nash, Aaron,Qi, Xiangbing,Maity, Pradip,Owens, Kyle,Tambar, Uttam K.

, p. 6888 - 6891 (2018)

A novel vinylogous Pictet–Spengler cyclization has been developed for the generation of indole-annulated medium-sized rings. The method enables the synthesis of tetrahydroazocinoindoles with a fully substituted carbon center, a prevalent structural motif in many biologically active alkaloids. The strategy has been applied to the total synthesis of (±)-lundurine A.
