- 中文摘要: Furylpyridines, thienylpyridines, and imidazolylpyridines were obtained regioselectively in 40 to 67% yields from the reaction of heteroaryllithiums with N- ethoxycarbonylpyridinium chloride or N-ethoxycarbonyl-3- methylpyridinium chloride in the presence of Cul in a catalytic amount at -78.degree.C or -50.degree.C, then followed by oxidation. The regioselectivity of this reaction depended upon temperature of the reaction and the nature of heteroaryllithium.
