Practical enantiospecific syntheses of lysobisphosphatidic acid and its analogues

J Org Chem. 2006 Feb 3;71(3):934-9. doi: 10.1021/jo051894e.

Abstract

We describe a versatile, efficient, and practical method for the preparation of enantiomerically pure lysobisphosphatidic acid (LBPA), bisether analogues, and phosphorothioate analogues of LBPA from solketal. Phosphorylation of a protected sn-2-O-oleoyl glycerol with 2-cyanoethyl bis(N,N-diisopropylamino)phosphite, followed by oxidation and deprotection, generated the enantiomers of 2,2'-LBPA. The corresponding phosphorothioate analogues were obtained by oxidation with sulfur. The (R,R) and (S,S) enantiomers of both LBPA and phosphorothioate LBPA were synthesized from (S)- and (R)-solketal, respectively. The ether analogue of (S,S)-lysobisphosphatidic acid (LBPA) and its enantiomer were synthesized from the same enantiomer (S)-solketal by simply changing the sequence of deprotection steps.
