water using D-glucose and KOH as green reagents is reported. The protocol is simple, inexpensive, scalable, and can be applied to different aromatic, heteroaromatic and sulphonyl azides. A high level of chemoselectivity is observed for azide reduction in the presence of other reducible functionalities like cyano, nitro, ether, ketone, amide and acid. The reaction gets completed in a short time (5–20
报道了使用D-葡萄糖和KOH作为绿色试剂将水中的叠氮化物还原为胺的快速有效方法。该方案简单,廉价,可扩展,可应用于不同的芳族,杂芳族和磺酰基叠氮化物。在其他可还原的官能团(如氰基,硝基,醚,酮,酰胺和酸)存在下,叠氮化物还原具有很高的化学选择性。反应可在短时间内(5–20分钟)完成,并以高收率(85–99%)提供胺。与常规加氢不同,该还原方案不需要任何金属催化剂,复杂的实验装置或使用高压设备。
