Derivatives of 2,3-anhydro-DL-threitol, 2,3-anhydroerythritol, 2,3:4,5-dianhydrogalactitol, and 2,3:4,5-dianhydroallitol.

alpha, omega-Disubstituted derivatives of 2,3-anhydro-DL-threitol (2), 2,3-anhydroerythritol (4), 2,3:4,5-dianhydrogalactitol (8), and 2,3:4,5-dianhydroallitol (12) have been synthesised by epoxidation of the appropriate alkeness and dienes. Benzyloxy carbonyl groups were used for protecting the primary hydroxyl groups during epoxidation.
