Grignard reagents react with vinylogous acyl triflates in toluene via an addition-fragmentation sequence to afford alkynyl ketones. A streamlined synthesis of (Z)-6-heneicosen-11-one, the sex pheromone of the Douglas fir tussock moth, illustrates the utility of this method.
格氏试剂通过加成-断裂序列与甲苯中的乙烯基三氟甲磺酸酯反应,得到炔基酮。(Z)-6-heneicosen-11-one(花旗松草蛾的性信息素)的简化合成说明了该方法的实用性。
