Total Synthesis of (±)-Gelsemine

Andrew Madin; Christopher J. O'Donnell; Taeboem Oh; David W. Old; Larry E. Overman; Matthew J. Sharp

A complex molecular reorganization (1-->2), a sequential anionic aza-Cope rearrangement and Mannich cyclization, and an unprecedented intramolecular Heck reaction of the tetrasubstituted double bond of a vinylogous carbamate are key steps in a new total synthesis of (+/-)-gelsemine (3). MOM=methoxymethyl, DBU=1,8-diazabicyclo[5.4.0]undec-7-ene.
