Selective functionalization of 1H-pyrrolo[2,3-b]pyridine (7-azaindole) at the 6-position was achieved by Reissert-Henze type reaction. Thus, halogeno (Cl, Br, I), cyano and thiocyanato groups were directly introduced to the pyridine ring of 7-azaindole.
通过Reissert-Henze型反应,成功实现了在1H-
吡咯并[2,3-b]
吡啶(7-氮
茚)的6-位进行选择性功能化。因此,
氯、
溴、
碘、
氰基和
硫氰酸基团被直接引入到7-氮
茚的
吡啶环上。
