Anionic Hetero[3,3]rearrangement. N-Acyl-N'-enylhydrazines to Pyrrolidinones
摘要:
N-Acyl-N'-enylhydrazines rearrange upon treatment with base to afford 5-amino-2-pyrrolidinones. The rearrangement can be rationalized in terms of initial stereospecific [3,3]sigmatropic shifts of the enolates followed by intramolecular addition of the nitrogen atom of the amide group to the imino group.
