Ene-iminium intermediates resulting from reaction between glyoxal and β-amino alcohols rearrange by an aza-Cope process. Three different tandem reactions are thus carried out; their first component is this cationic rearrangement, the second step being either an iminium hydrolysis, a nucleophile-induced ene-iminium cyclization or a Mannich reaction. The last two sequences lead to homochiral proline
由乙二醛和β-氨基醇之间的反应产生的乙炔亚胺中间体通过aza-Cope工艺重排。因此进行了三种不同的串联反应。它们的第一个成分是阳离子重排,第二个步骤是亚胺水解,亲核试剂诱导的烯-亚胺环化或曼尼希反应。最后两个序列导致同手性脯氨酸衍生物。
