1,1-Dichloro-3-methylsulfonyl-3-methylthio-1,2-propadiene, generated in situ under basic conditions, reacted with a 4-iodomethylazetidinone to give a carbapenam. Subsequent efforts to convert this material to a Δ-2-carbapenem by rearrangement of an allylic sulfoxide led instead to the formation of a novel Δ-1-carbapenem.
在碱性条件下原位生成的1,1-二氯-3-甲基磺酰基-3-甲基硫基1,2-丙二烯与4-碘甲基氮杂环丁酮反应生成碳青霉烯。随后通过将烯丙基亚砜重排而将该材料转化为Δ-2-卡培南的努力导致形成新的Δ-1-卡培南。
