The enantioselective total synthesis of the nonacyclic polypyrrolidinoindoline (-)-idiospermuline is described. Stereocontrolled formation of the vicinal quaternary carbon centers is achieved in a single step by dialkylation of an unsymmetrical prostereogenic dienolate with a tartrate-derived chiral dielectrophile. A catalyst-controlled diastereoselective Heck cyclization is employed to form the diaryl-substituted quaternary center. (C) 2003 Elsevier Ltd. All rights reserved.
