The [(4-methoxycarbonylthiazolidino)carbonyl-dihalomethyl]phenylmercury compounds 2a,b and 5a,b have been synthesized. When heated in refluxing bromobenzene they form halogenated penicillin analogs. (--)-Methyl 6-epi-6-bromobisnorpenicillinate (3a) and methyl 6-epi-6-bromopenicillinates (6a,b) have been prepared and isolated.
合成了[(4-甲氧基羰基噻唑烷)羰基-二卤甲基]苯基汞化合物2a,b和5a,b。在回流的溴苯中加热时,它们会形成卤代青霉素类似物。已经制备并分离了(-)-6-epi-6-溴双去甲膦酸甲酯(3a)和6-epi-6-溴openicilliates甲基(6a,b)。
