A new method for the synthesis of 1-aryl-2,3-diaroyl cyclopropanes has been developed by iodine/DBU-mediated cyclization of 1,3,5-triaryl-1,5-diketones. The alcohols derived by the reduction of these cyclopropanes, when treated with conc. HCl, afforded a series of 1,3-dienes through cyclopropyl ring-opening and subsequent fragmentation. Overall, the synthetic sequence represents a new non-Wittig methodology
通过碘/DBU介导的1,3,5-三芳基-1,5-二酮的环化,开发了一种合成1-芳基-2,3-二芳酰基环丙烷的新方法。当用浓溶液处理时,通过还原这些环丙烷而衍生出醇。 HCl 通过环丙基开环和随后的裂解得到一系列 1,3-二烯。总体而言,该合成序列代表了一种从 1,5-二酮合成 1,3-二烯的新非维蒂希方法。
