One-pot synthesis: An efficient amino-directed one-pot synthesis of N-H carbazoles from unprotected 2-aminobiaryl compounds is reported. The free amino unit acts as both a directing group for ortho C-H activation and a functional group for construction of an N-heterocyclic ring (see scheme).
报道了一种从未保护的 2-氨基联苯化合物高效进行氨基导向的一锅合成 N-H 咔唑的方法。游离氨基单元既充当了邻位 C-H 活化的导向基团,又作为构建 N-杂环的官能团(见方案)。
