Abstract o-Isopropenyl phenoxyactic acids 1 and 8 on treatment with thionyl chloride followed by aqueous workup furnished the acylated products 4 and 9 in moderate yields. The corresponding acid chlorides could also be cyclised with stannic chloride. The acid chlorides from 10 and 11 however did not undergo cyclisation.
摘要 邻异丙烯基苯氧基乙酸 1 和 8 用亚硫酰氯处理,然后进行水处理,以中等收率提供酰化产物 4 和 9。相应的酰氯也可以与氯化锡环化。然而,来自 10 和 11 的酰氯没有进行环化。
