Synthesis of (-)-Slaframine and Related Indolizidines
Pearson, William H.,Bergmeier, Stephen C.,Williams, John P.
, p. 3977 - 3987 (2007/10/02)
An enantioselective synthesis of the indolizidine alkaloid (-)-slaframine 1 is reported.Reductive double cyclization of the azido epoxy tosylate 48 afforded the indolizidine 52, which was converted to (-)-slaframine in two steps.The cyclization substrate
