Photochemical reactions of naphthoquinones triggered by 1,6-hydrogen atom transfer have been developed. This reaction proceeds in stereospecific manner without loss of the stereochemical information of the substrate, enabling the enantioselective total synthesis of preussomerin EGs. The constructed spiroacetal center is the sole stereogenic center in the product, which had been previously impossible
已经开发了由 1,6-氢原子转移引发的萘醌的光化学反应。该反应以立体有择的方式进行,而不会丢失底物的立体化学信息,从而实现前乌素 EG 的对映选择性全合成。构建的螺缩醛中心是产品中唯一的立体中心,以前无法通过利用常规方法来设置。
