## Abstract [(Benzyloxy)(benzyloxycarbonyl)methyl]triphenylphosphonium bromide (8), obtained from glyoxylic acid via a convenient oneβpot procedure, reacted in a Wittig reaction with 4β__O__βbenzylβ2,3:5,6βdiβ__O__βisopropylideneβDβmannose (7), readily synthesized on a large scale from Dβmannose, t
KDO (1) is synthesized in five steps, starting from 1,2-to the carbonate 9. Silicon-induced lactonization affords the lactone 10, which can be converted into NH 4 -KDO by anhydro-3,4:5,6-di-O-isopropylidene-D-mannitol ( 6). The epoxide 6, obtained from D-mannitol (2), reacts with lithiated standard
