body circulation of Omeprazole (irreversible proton pump inhibitor), we disclose the carbene-triggered cascades for the synthesis of 2-aminobenzofuran derivatives from N-sulfonyl-1,2,3-triazoles or benzothioazole-bearing thiocarbamates, which represents an unprecedented imine derivative migration process. Furthermore, the desulfurizing reagent-free Barton–Kellogg-type reactions starting from N-sulfonyl-1
受奥美拉唑(不可逆质子泵抑制剂)体内循环的启发,我们公开了卡宾触发的级联反应,用于从N-磺酰基-1,2,3-三唑或含苯并噻唑的硫代氨基甲酸酯合成 2-氨基苯并呋喃衍生物。前所未有的亚胺衍生物迁移过程。此外,还首次实现了以N-磺酰基-1,2,3-三唑为原料的无脱硫剂 Barton-Kellogg 型反应,并证实元素硫是该转化过程中的副产物。实验数据和 DFT 计算都进一步彻底解释了独特的反应性。
