formation of methylenebis(chalcone)s has been discovered during deprotection with methoxymethyl groups from trihydroxychalcones. Studies on this methylenation reaction led to a mechanism hypothesis that was extended to other chalcones and to dihydrochalcone, acetophenone, benzophenone and flavone derivatives. This new method was applied to the rapid synthesis of natural product piperanduncin C. These original
在用来自三羟基查耳酮的甲氧基甲基基团去保护过程中发现了亚甲基双(查耳酮)的形成。对该亚甲基化反应的研究导致了一种机制假设,该假设扩展到其他查耳酮和二氢查耳酮、苯乙酮、二苯甲酮和黄酮衍生物。将这种新方法应用于天然产物哌兰霉素 C 的快速合成。还评估了这些原始亚甲基双化合物的抗寄生虫活性。
