The Favorskii rearrangement of α-chloro β-keto sulfones, which are easily synthesized from aldehydes and ketones, with amines gives β-sulfonyl amides in good yield. These β-sulfonyl amides are converted to amides and α,β-unsaturated amides by reduction or elimination of the sulfonyl group.
很容易由醛和酮与胺合成的α-氯代β-酮砜的Favorskii重排反应可得到高产率的β-磺酰基酰胺。通过还原或消除磺酰基,将这些β-磺酰基酰胺转化为酰胺和α,β-不饱和酰胺。
