Unsymmetrical, disubstituted maleimide and maleic anhydride frameworks have been accessed from Baylis–Hillman adducts in an operationally simple three‐step (Friedel–Crafts reaction, selective hydrolysis, and cyclization), one‐pot strategy. This strategy has been successfully extended to the synthesis of a representative bioactive compound, himanimide A (see scheme).
不对称,二取代的马来酰亚胺和顺丁烯二酸酐骨架可通过操作简单的三步操作(弗里德-克拉夫茨反应,选择性水解和环化),一锅法从拜利斯-希尔曼加合物中获得。该策略已成功地扩展到代表性生物活性化合物喜马拉尼A(参见方案)的合成。
