Sažetak

A method for the preparation of S-benzyl-N-phthaloyl-L-cysteine with [a]D -167° is described. According to the previously described procedure for the preparation of racemic S-benzyl-N-phthaloyl-cysteine aldehyd ,
the optically active compound was obtained showing [a]D - 103°. The following new compounds were prepared : S.-benzyl-N-phthaloyl-L-cysteine aldehyde ethylene acetal, S-benzyl-L-cysteine aldehyde ethylene acetal, picrate of S-benzyl-L-cysteine aldehyde ethylene acetal, and 5-benzylthio-4-phthalimidopent-2-enoic acid, the vinylogue of S-benzyl-N-phthaloyl-cysteine.
