sieves, results in the formation of β-hydroxyamines through the 1,3-electrocyclisation of an azomethine ylide and the subsequent ring-opening hydrolysis of an aziridine. The intermediacy of an azomethine ylide in this process is suggested by the isolation of oxazolidines from the cycloaddition of the azomethine ylides to their aldehyde precursors.
在存在4Å分子筛的情况下,将杂芳基甲醛和N-烷基氨基酸的混合物在干燥的甲苯中回流,通过偶氮甲基内酯的1,3-电环化反应形成β-羟胺,随后开环氮丙啶的水解。在此过程中,通过将恶唑烷与恶唑烷的环加成至其醛前体中分离出了恶唑烷,表明了甲乙胺的中间体。
