Abstract

2-[2′-Methyl-4′-aminopyrimidyl-(5′)]-methylformamino-5-hydroxy-Δ2-pentenylaryl disulfides (thiamine aryl disulfides) were prepared by the application of arylsulfenyl chloride, aryl arylthiosulfonate, and aryl thiothiocyanate to the thiol type of vitamin B1, and homothiamine aryl disulfides were prepared in the same manner using homovitamin B1. Thiamine alkyl disulfides were obtained from the thiol type vitamin B1 and alkyl-sulfenyl chloride and alkyl or aralkyl thiosulfonate.
