Abstract

Abstract: The efficient and regioselective synthesis of various bisheterocyclic compounds was performed using a regioselective onepot lithiation–transmetallation–cross-coupling of 2- methoxypyridine. Key words: C-6 lithiation, cross-coupling of heterocycles, 2-methoxy-6- (tributylstannyl) pyridine, 6-bromozinc-2-methoxypyridine
