Synthesis of C2-symmetric bisthiazolidine ligands derived from L-cysteine
Diaz,Gonzalez
, p. 1697 - 1705 (2001)
Treatment of L-cysteine esters and thiazolidine-4-carboxylic esters with an excess of paraformaldehyde in the presence of trifluoroacetic acid provides C2-symmetric N,N′-methylene-bisthiazolidines in good yield.
Thiazolidine esters: New potent urease inhibitors

A variety of esters of thiazolidine-4-caboxylic acid were synthesized and investigated for their urease inhibitory properties. A significant increase in urease inhibitory activities of these ester derivatives has been observed. The order of activity increases from methyl ester to heptyl ester but further prolongation of the alkyl chain was proved to be detrimental for receptor binding. These findings provide evidence that the nature of the alkyl chain has a significant impact on the coordination of thiazolidine esters with bi-metallic nickel center of urease. It was also observed that inhibition potentiated by lower pH and with increase in time.
Sulfur-containing β-amino alcohols as catalysts in enantioselective synthesis
Trentmann, Wilhelm,Mehler, Thomas,Martens, Juergen
, p. 2033 - 2043 (2007/10/03)
Oxazaborolidine catalysts generated in situ from cyclic or acyclic sulfur containing (R)-cysteine, (S)-penicillamine and (S)-methionine derivates and BH3 have been applied successfully to the enantiocontrolled, catalytic reduction of aromatic ketones. The corresponding sec alcohols could be obtained in excellent enantiomeric excess, up to 100% ee. Using these chiral auxiliaries in the enantioselective addition of diethylzinc to aldehydes afforded optically active sec alcohols in enantiomeric excess up to 93% ee.
