title: [Synthesis of the bis(S-methoxycarbonylthio)-B-chain of beef insulin (author's transl)].
abstract: The bis(S-methoxycarbonylthio)-B-chain of beef insulin was synthesized from B-chain bis(S-sulfonate) and methoxycarbonyl-sulfenylchloride and reacted with thioglycolic acid as well as with cysteine in acidic solution to the corresponding unsymmetrical disulfides in 80% yield.
