Total synthesis of (-)- and ent-(+)-vindoline

Org Lett. 2005 Sep 29;7(20):4539-42. doi: 10.1021/ol051975x.

Abstract

[reaction: see text] Two exceptionally concise total syntheses of (-)- and ent-(+)-vindoline are detailed enlisting a diastereoselective tandem [4 + 2]/[3 + 2] cycloaddition of a 1,3,4-oxadiazole. The unique reaction cascade assembles the fully functionalized pentacyclic ring system of vindoline in a single step that forms four C-C bonds and three rings while introducing all requisite functionality and setting all six stereocenters within the central ring including three contiguous and four total quaternary centers.
