3-Alkyl-2-phenyl-1-vinylpyrroles from ketoximes and acetylene: an improved synthesis by the Trofimov reaction
摘要:
A one-pot synthesis of 3-alkyl-2-phenyl-1-vinylpyrroles, giving high yields at atmospheric pressure, was developed on the basis of reacting alkyl phenyl ketoximes with acetylene in a KOH-DMSO system (the Trofimov reaction).

A variety of 2-arylbenzofurans were obtained in good yields by the O-arylation of oximes with diaryliodonium triflates, followed by the treatment with HCl in dioxane under warming conditions through the [3,3]-sigmatropic reaction. The present reaction is one-pot transition metal-free method for the preparation of various 2-arylbenzofurans from oximes, which are easily available from the reaction of alkyl aryl ketones with hydroxylamine
