Desymmetrization-based protocols for the synthesis of highly functionalized indeno-spirocyclopropanes and cyclopropa-fused indanes have been established through unexpected reactions triggered by the Corey-Chaykovsky reagent. These structures were further elaborated in one step to privileged scaffolds such as fluorenones, indenones, and naphthaphenones. For instance, an acid-catalyzed transformation
通过Corey-Chaykovsky试剂引发的意外反应,已经建立了基于去对称化的合成高度官能化的茚-螺环丙烷和环丙烷稠合的茚满的方案。将这些结构一步一步地加工成荧光素,茚三酮和萘甲酮等特有的支架。例如,腺苷-螺环丙烷的酸催化转化通过均一纳扎罗夫型环化提供芴酮,而萘甲酮通过酸催化的环丙烷开环/复古-迈克尔序列获得。
