Acid-catalyzed tandem reactions of atropaldehyde acetals were established for the synthesis of three important molecules, 2,2-disubstituted indolin-3-ones, naphthofurans and stilbenes. The synthesis was realized using novel reaction cascades, which involved the same two initial steps: (i) SN2′ substitution, in which the atropaldehyde acted as an electrophile; and (ii) oxidative cleavage of the carbon–carbon

醛类产物的碳-碳键的氧化裂解。与文献方法相比,本协议不仅避免使用昂贵的
贵金属催化剂,而且操作简单。
