propiolate and ethyl buta-2,3-dienoate with cyclohexanone induced by SmI2 occurred either at α- or β-position to yield different products depending on with or without a proton source. The synthesis of terpenic acid was demonstrated using this reaction.
SmI 2诱导的丙酸甲酯和2,3-丁二酸丁酸乙酯与环己酮的反应发生在α-位置或β-位置,根据有无质子源产生不同的产物。使用该反应证明了萜烯酸的合成。
