Free-radical reactions of carbohydrate derivatives in the synthesis of carbocyclic compounds 3. Cyclization of methyl 3-O-benzyl-6-bromo-4,6-dideoxy-2-methoxycarbonylmethylene-α(β)-D-erythro-hexoparanosides and methyl 3,4-di-O-benzyl-6-bromo-6-deoxy-2-met

The effect of substituent at C(4) of the pyranose ring in 3,4-disubstituted carbohydrate derivatives on the process of their intramolecular free-radical C(2)-C(6) cyclization was demonstrated.The absence of the effect of the C(1) and C(3) centers on the r
