摘要

两种缺电子成分之间的电子错配 Diels-Alder 反应在合成上非常有用，但在热条件下却没有得到充分发展。本文介绍了烯酮与多种缺电子二烯的光诱导正式[4 + 2]环加成反应。这种循序渐进的方法成功的关键在于通过多样化的机理途径对基于环丁烷的杂交中间体进行 C - C 键裂解/重排。基于这种环化方法，可通过九个步骤实现露地分散酮的全合成。

Photoinduced formal [4 + 2] cycloaddition of two electron-deficient olefins and its application to the synthesis of lucidumone

Electronically mismatched Diels−Alder reaction between two electron-deficient components is synthetically useful and yet underdeveloped under thermal conditions. Herein, a photoinduced formal [4 + 2] cycloaddition of enone with a variety of electron-deficient dienes is described. Key to the success of this stepwise methodology relies on a C − C bond cleavage/rearrangement of the cyclobutane based overbred intermediate via diversified mechanistic pathways. Based on this annulation method, total synthesis of lucidumone is achieved in nine steps.
