(R)- and (S)-glyceraldehyde and glycerol derivatives have been prepared from (2R,3S)-1,2-O-isopropylidenebutane-1,2,3,4-tetrol. (2R,3S)- and (2S,3S)-1,2-O-benzylidenebutane-1,2,3,4-tetrol have been prepared and cleaved to give (R)- and (S)-1,2-O-benzylideneglyceraldehydes and -glycerols.The conservation of chirality and conversion to PAF analogues are also demonstrated.

Benzylidene acetals of 1,2- and 1,3-glycols are easily cleft by diisobutylaluminum hydride in a toluene solution at 0 deg C - room temperature to give the corresponding monobenzyl ethers of the glycols.In general the reaction proceeds excellently in regioselective manner depending on the stereochemical environment.
