Additive Pummerer rearrangement of methyl cyclopentylidene(phenylsulphinyl)-acetate induced by acetyl chloride, trifluoroacetic anhydride, or thionyl chloride
Abstract
Methyl cyclopentylidene(phenylsulphinyl)acetate, on treatment with acetyl chloride, trifluoroacetic anhydride, or thionyl chloride, undergoes an additive-type Pummerer rearrangement to give αβ-difunctionalised phenylthio-derivatives.
