Autor: R. A. Skolmeistere, T. F. Petrushina, L. Ya. Leitis, U. G. Ibatullin, I. N. Plesanova, M. V. Shimanskaya, M. G. Safarov

Publikováno v: Chemistry of Heterocyclic Compounds. 25:663-666

Heterocycles containing one or two atoms of oxygen are synthesized by the condensation of pyridine carboxaldehydes with ethylene glycol, 1,3-propanediol, and 3-methyl-3-buten-1-ol. When the unsaturated alcohol is used, linear acetals are formed along
