Abstract

Asymmetric syntheses of l-homocysteine 1 and l-homocystine 2 are described. Alkylation of the carbanion derived from Schöllkopf reagent 3 and ensuing hydrolyses gave S- triphenylmethyl-l-homocysteine 6. Removal of the triphenylmethyl group gave l- homocysteine 1 and subsequent oxidation provided l-homocystine 2.
