摘要
Alkylative cycloisomerization of N,N-diallylpropiolamide into alpha-alkyhdene-gamma-lactams was mediated by dialkylzinc reagents in aerobic medium. In the presence of an alkyl iodide, final oxidation by iodine-atom transfer predominates over reductive zincation. The dialkylzinc-mediated radical process tolerates the presence of the acidic terminal alkyne.
