The synthetic route starts from penicillin G, peroxyacetic acid(8.5%) as Oxidizing Agent to get penicillin G sulfoxide; esterifided with p-nitrobenzyl bromine to synthesize penicillin G sulfoxide ester; we synthesize 3-exomethylenecepham sulfoxide ester with phthalimide potassium and 4A molecular sieve as acid scavenger to open the ring, SnCl_4 as catalyzation to close the ring. The yield is over 60%.
本研究采用的合成路线为:以青霉素G钾盐为原料,选用工业过氧化氢制备的过氧乙酸(22.3%)稀释至8.5%为氧化剂,氧化得青霉素亚砜;采用对硝基溴苄为酯化试剂,制备青霉素亚砜酯;以NCP(N-氯代邻苯二甲酰亚胺)为开环试剂,酞酰亚胺钾和4A型分子筛为酸清除剂,顺利开环;再经无水SnCl_4催化闭环得3-环外亚甲基头孢亚砜酯,最终产率在60%以上。
