spiranic β-lactams which undergo CN bond cleavage during chromatography on alumina giving cycloalkenones functionalized at position 3. This new rearrangement has been applied to the synthesis of α-amino-β,γ-unsaturated amides in one step and gives convenient yields.
N-链烷醇-β-烯胺的辐射导致形成螺环的β-内酰胺,在氧化铝色谱上进行CN键裂解,生成在3位官能化的环烯酮。这种新的重排方法已应用于α-氨基的合成一步合成-β,γ-不饱和酰胺,收率方便。
