SYNTHESIS OFC2-SYMMETRIC BISTHIAZOLIDINE LIGANDS DERIVED FROM L-CYSTEINE
摘要:
Treatment of L-cysteine esters and thiazolidine-4-carboxylic esters with an excess of paraformaldehyde in the presence of trifluoroacetic acid provides C-2-symmetric N,N'-methylenebisthiazolidines in good yield.

The synthesis of N, O, S protected forms of (R)-cysteine and (R)-cysteinol as bicyclic derivatives is described. The reactivity and the preparation of substituted derivatives of these systems is also discussed.
