An efficient, one-pot approach has been established for synthesizing a wide range of 3-amino-[1,2,4]-triazolo pyridines and related heterocycles from the electrochemically induced desulfurative cyclization of 2-hydrazinopyridines with isothiocyanates. The protocol allows for the formation of C–N bonds under simple conditions without transition metals or external oxidants. The practicability of this
已经建立了一种有效的一锅法,用于通过电化学诱导的 2-肼基吡啶与异硫氰酸酯的脱硫环化合成各种 3-氨基-[1,2,4]-三唑并吡啶和相关杂环。该协议允许在没有过渡金属或外部氧化剂的简单条件下形成 C-N 键。该策略的实用性体现在其广泛的底物范围、良好的官能团相容性和克级合成。3-氨基-[1,2,4]-三唑并吡啶的后期修饰使我们能够获得几种具有有效抗癌活性的分子。
