title: Synthesis of L-cysteine derivatives of immunotropic activity.
abstract: Working on the problem entitled "Synthesis of cysteine derivatives of immunotropic activity" the following compounds were synthesized; cysteine hydrazide and its hydrochloride, S-methylcysteine hydrazide hydrochloride, S, N, N-trimethylcysteine and S-benzylcysteinyl-S-benzylcysteine. We modified the synthesis of cysteine hydrazide and prepared its hydrochloride. This way a better yield and simplification of the synthesis were achieved. The above compounds were obtained with good yields.
