Chemistry of sulfonylmethyl isocyanides. 37. Synthesis of 3,4-disubstituted pyrroles bearing substituents of electron-withdrawing and/or electron-donating nature
摘要:
The synthesis is described of a series of 3,4-disubstituted pyrroles 8 from 1-isocyano-1-tosyl-1-alkenes and a variety of Michael donors. It is possible to use this method for the synthesis of pyrroles that bear no electron-withdrawing substitutents.
