A series of analogs of the natural mitostatic agent combretastatin were synthesized by the reaction of nitrile oxides with natural allylbenzenes, such as myristicin, apiol, and dillapiol. The 1,3-dipolar cycloaddition reactions in allylic systems proceed regiospecifically. The reactions with trans isomers of propenylbenzenes, viz., isomyristicin, isoapiol, and isodillapiol, as dipolarophiles produce regioisomers.
通过腈氧化物与天然烯丙基苯(如肉豆蔻苷、芹醇和莳萝酚)的反应,合成了一系列天然抗丝裂霉素类似物。烯丙基系统中的 1,3-二极环加成反应具有区域特异性。与丙烯基苯的反式异构体(即异肉豆蔻苷、异芹醇和异莳萝酚)作为双极亲和剂进行的反应会产生区域异构体。
