A Convenient Synthesis of (1H-Azol-1-yl)piperidines
摘要:
A convenient preparation of 3- and 4-(1H-azol-1-yl)piperidines by arylation of azoles (i.e., pyrazoles, imidazoles, and triazoles) with 3- and 4-bromopyridines and subsequent reduction of the pyridine ring was developed. The method was extended to benzo analogues of the title compounds.

copper(I) oxide catalyzed N‐arylation reaction performed in MeOH at room temperature for the synthesis of N‐substituted azoles and amines was extended to the heterocyclic series, i.e., we report herein the base‐free copper(I) oxide catalyzed N‐heteroarylation of 1H‐(benz)imidazole, by means of electron‐rich or electron‐deficient B‐heteroarylboronic acids or 2‐heteroaryl‐4,4,5,5‐tetramethyl‐1,3,2‐dioxaborolanes
