## Abstract The enantiopure epoxides 2โ€“6 were synthesized from 1,2;5,6โ€diโ€Oโ€isopropylideneโ€Dโ€mannitol (1). The terminal epoxides 2 and 3 are available from the desoxy mannitol 9 in three steps. The __C__~2~โ€symmetrical epoxides 4 and 5 were generated via the Cโ€4โ€inverted alcohol 15. The __C__~2~โ€sy
