Free radical telomerization of vinylene carbonate with bromoform (and carbon tetrabromide) afforded two isomeric telomers, dibromomethylene-4,4'-bis (5-bromo-1,3-dioxolan-2-one) (5a, b) as two fold addition products in addition to the 1 : 1 adducts. On the similar treatment, this type of products (7a, b 9a, b) was obtained from 5-substituted-4-tribromomethyl-1,3-dioxolan-2-ones. A sequence of reactions involving methanolysis and reductive photolysis to give methyl 5-methoxypyranosides permitted the stereochemical assignment of 5a and b as dl (anti)-and meso (syn)-configurations, respectively.
