Abstract
Improvements in the synthesis process of cystine, object of the main patent, characterized by the fact that a disulfide of bis- (alpha-amino-alpha.alpha-dicarbalkoxy-ethyl), of free or amidified animate group, is prepared, preferably, the bis- (alpha-formylamido-alpha.alpha-dicarbethoxy-ethyl) disulfide in anhydrous ethanolic medium, the ethanol is then removed by distillation and the residue from the distillation is subjected to a decarboxylating hydrolysis.
