The synthesis of the indolizidine alkaloid, (+)-lentiginosine, is described. A key feature of the preparative route is the efficient and stereoselective construction of a dihydroxylated pyrrolidine via Sharpless asymmetric dihydroxylation of an aziridine-enoate, which was prepared from commercially available 1-(S)-α-methylbenzylaziridine-2-methanol. In addition, a regioselective aziridine-to-pyrrolidinone ring expansion process followed by a Wittig olefination was employed to construct a late stage pyrrolidine intermediate that was transformed into (+)-lentiginosine.
