Reaction of vinylpyridines with oxazoles

Depending on the structure, the reaction of the hydrochlorides of 2- and 4-vinylpyridines and 2-methyl-5-vinylpyridine with oxazoles leads to the synthesis of dipyridyls with or without a hydroxy group. It is shown that the regiospecificity of the reaction can be predicted on the basis of quantum-chemical calculations with the aid of the concepts of MO perturbation theory.Deceased.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 9, pp. 1255–1262, September, 1980.
