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.

corresponding lactams via aerobic dehydrogenation and oxidative coupling with water. The mild reaction conditions tolerate diverse functional groups, enabling application to molecules that cover broad chemical space. The method is showcased in selective functionalization of buildingblocks and complex molecules, including late-stage functionalization of bromodomain inhibitors.
