A versatile approach to 3-alkyl and 2,3-dialkylpyrroles
摘要:
A route is described towards N-benzoyl-3-alkyl and N-benzoyl-2,3-dialkyl pyrroles from alpha -amido-ketones via an intramolecular Wittig reaction to afford 4-phenylthio-3-pyrrolines which are then oxidised to the corresponding sulphones and aromatised by treatment with potassium t-butoxide.
