A new synthesis of alkyl 1-alkyl-2-methylpyrrole-3-carboxylates by ring transformation of 2-chloro-2-acetimidoylbutyrolactones
摘要:
Reaction of 2-chloro-2-acetimidoylbutyrolactones with sodium methoxide or sodium ethoxide in the corresponding alcohol provides a facile one-step synthesis of methyl or ethyl 1-alkyl-2-methylpyrrole-3-carboxylates from readily available starting materials.
