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).
