Abstract

Procedure for the obtaining of quiral derivatives of tetrahidro-2H-piran-2-ona, of formula (I), in which r and r are chlorine or rent c <-; and r can be one of various types of radicals. It consists in the treatment of the compound of formula (II), where r is alkyl c <-; r is bencilo, 4-fluorbencilo or 4-metoxibencilo and r, r and r are the same as in the formula (I), at 45-80 c in the presence of a base, in a liquid aromatic hydrocarbon; following treatment with a paladium hydroxide catalyst on carbon; reaction with acous dissolution of acetic acid; and treatment with an oxidizing agent in an inert solvent. These compounds have pharmacological applications as anti-hypercholesterolemic. (Machine-translation by Google Translate, not legally binding)
