With α,β-enoates and aldehydes, methyl 3-lithio-2-methyl-3-phenylthio-2-propenoate undergoes addition and cyclization yielding functionalized cyclopentenones and butenolides, respectively. Reaction with acyl chlorides gives γ-keto-α,β-enoates.
使用 α,β-烯酸酯和醛,3-lithio-2-methyl-3-phenylthio-2-propenoate 进行加成和环化,分别产生官能化的环戊烯酮和丁烯内酯。与酰氯反应生成γ-酮-α,β-烯酸酯。
