Enantio- and diastereoselective one-pot synthesis of three- to seven-membered cis-azaheterocycles was achieved using a triggered asymmetric conjugate addition reaction of lithium amide with an enoate, followed by alkylation of the resulting lithium enolat

(Chemical Equation Presented) The antipsychotic compound nemonapride 1 was synthesized in nine steps from D-alanine 2. The key steps for the synthesis of the 3-aminopyrrolidine moiety include a Birch reduction of a cyclic enaminoester and the reduction of a pyrrolidinone to the pyrrolidine 7. Final coupling with the benzoic acid derivative 9 gave 1 as a single enantio- and diastereomer.

The first asymmetric synthesis of (2R,3R)-3-amino-1-benzyl-2-methylpyrrolidine, the parent diamine of antipsychotic agent, emonapride, from (S)-malic acid was achieved via a highly diastereoselective reductive alkylation.
