Investigations on Pantothenic Acid and Its Related Compounds. XIII. Chemical Studies. (6). Syntheses of Homopantethine and Some Other Pantethine Analogs

Abstract

Four pantethine analogs (homopantethine (VII), α-methyl-(XIIIb) and β-methyl-pantethine (XIIIc), and oxypantetheine (XVI)) were prepared. Synthesis of VII from D-pantothenonitrile (I) and homocysteamine by using the thiazine derivative (III) as an intermediate was established. XIIIb and XIIIc were synthesized by the thiazoline method described previously, and XVI by the general method.
