A facile, convenient, and two step strategy for synthesis of spirooxindoles containing α-arylidene-γ-butyrolactone moiety has been developed via monoalkylation of 2-oxindoles with Baylis-Hillman acetates followed by the spirolactonization of the resulting cinnamic esters on treatment with phenyliodine (III) bistrifluoroacetate (PIFA).

有机合成中的Baylis-Hillman乙酸酯：羟吲哚-螺-α-亚芳基-γ-丁内酯框架的简单两步策略

通过将2-氧吲哚与Baylis-Hillman乙酸酯进行单烷基化，然后将生成的肉桂酸酯经苯碘化处理进行螺内酯化，已经开发了一种简便，方便且分两步的方法，用于合成含有α-亚芳基-γ-丁内酯部分的螺硫辛多酯。 III）双三氟乙酸盐（PIFA）。
