A stereocontrolled synthesis of azetidinone 3 as a key intermediate to 1β-methylcarhapenem 2 has been achieved via iodoamidation of trichloroacetimidate prepared from (Z)-olefinic allylic alcohol 6, aziridine ring-openingreaction with cyanide nucleophile and a tandem β-lactam formation.
氮杂环丁酮 3 作为 1β-甲基碳青霉烯 2 的关键中间体的立体控制合成已通过由 (Z)-烯丙醇 6 制备的三氯乙酰亚胺酯的碘酰胺化、氮丙啶与氰化物亲核试剂的开环反应和串联 β-内酰胺形成实现。
