N-diallylpropiolamide into α-alkylidene-γ-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. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
N,N-二烯丙基丙酰胺向α-亚烷基-γ-内酰胺的烷基化环异构化是由需氧介质中的二烷基锌试剂介导的。在烷基碘的存在下,碘原子转移的最终氧化作用优于还原性锌化作用。二烷基锌介导的自由基过程耐受酸性末端炔烃的存在。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
