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.
制备了四种泛硫乙胺类似物(高泛硫乙胺(VII),α-甲基泛硫乙胺(XIIIb)和β-甲基泛硫乙胺(XIIIc),以及氧化泛硫乙胺(XVI))。通过使用噻嗪衍生物(III)作为中间体,从D-泛硫腈(I)和高胱胺合成VII。使用先前描述的噻唑啉方法合成XIIIb和XIIIc,通过常规方法合成XVI。
