The cesium carbonate-mediated reaction of 2-bromoallyl sulfones and ortho-hydroxychalcones furnished 3-arylsulfonyl-4H-chromene derivatives in 58-67% yield (18 examples). 2-Bromoallyl sulfones functioned as synthetic surrogates for allenyl sulfones in the reaction.
碳酸铯介导的2-溴烯丙基砜与邻羟基查耳酮的反应以58 - 67%的产率得到了3-芳基磺酰基-4H-色烯衍生物(18个实例)。在该反应中,2-溴烯丙基砜作为联烯基砜的合成替代物。
