Free-radical reactions of carbohydrate derivatives in the synthesis of carbocyclic compounds

The decisive influence of the carboxyl group on the methanolysis of 3-methoxy-4-methoxycarbonylmethyl-2-oxabicyclo2.2.1.]heptanes was proved experimentally, and several routes of conversion of the latter to the corresponding cyclopentanes were found.For Communication 1 see Ref. ¹ This work was partially supported by the Russian Foundation for Fundamental Research.Translated fromIzvestiya Akademii Nauk.
