A N-iodosuccinimide (NIS)-promoted [3 + 2] annulation reaction of aryldiazonium salts with guanidines has been developed for the construction of previously elusive 2-aryl-5-amino-2H-tetrazoles. This transformation takes advantage of readily available starting materials, proceeds under metal-free, mild, and robust conditions, and holds broad functional group compatibility. The utility of this protocol
甲Ñ碘代丁二酰亚胺(NIS)促进的[3 + 2]胍芳基重氮盐的环反应已为先前的难以捉摸的2-芳基-5-氨基-2-施工开发ħ -tetrazoles。这种转化利用容易获得的起始材料,在无金属、温和且稳定的条件下进行,并具有广泛的官能团兼容性。该协议的效用通过耦合、环化、脱氨基和脱氮衍生化得到进一步体现。
