摘要

在丙炔醛和氧化膦之间建立了一种高效的磷醛/Meyer-Schuster重排级联反应，以中高收率得到了各种磷酰烯酮。一系列综合的机理实验，包括关键中间体的鉴定和18O同位素标记的应用，证实了该级联反应是通过磷酸-醛醇级联反应进行的，然后是Meyer-Schuster重排级联反应。

Acid-Promoted Phosphorylation of Ynones for the Synthesis of Phosphoryl Enones

An efficient phospha-aldol/Meyer-Schuster rearrangement cascade reaction between propargylic aldehydes and phosphine oxides has been developed in which various phosphoryl enones were obtained in moderate to excellent yields. A comprehensive series of mechanistic experiments, including the identification of key intermediates and the application of ¹⁸O isotope labeling, has confirmed that this cascade reaction proceeds through a phospha-aldol followed by Meyer–Schuster rearrangement cascade reaction.

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
