A total synthesis of (-)-slaframine from (+)-cis-(2R,3S)-3-hydroxyproline

A total synthesis of the naturally occurring indolizidine (-)-Slaframine 4 has been achieved, starting from the cis-3-hydroxyproline derivative 1, in which a key step is a Julia olefination reaction using the dianion derived from the β-aminosulfone 5.
