## Abstract [(Benzyloxy)(benzyloxycarbonyl)methyl]triphenylphosphonium bromide (8), obtained from glyoxylic acid via a convenient one‐pot procedure, reacted in a Wittig reaction with 4‐__O__‐benzyl‐2,3:5,6‐di‐__O__‐isopropylidene‐D‐mannose (7), readily synthesized on a large scale from D‐mannose, 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
