A SIMPLE, GENERAL AND EFFICIENT METHOD FOR O AND N-RETINOYLATION. APPLICATION TO THE SYNTHESIS OF 2-RETINOYL-LECITHIN.

Abstract The synthesis of the new l-stearoyl-2-retinoyl-glycero-3-phosphorylcholine by coupling of retinoic acid and lysolecithin with DCC-DMAP (1.2 eq.) is reported. This method is applied to O and N-retinoylation of uncharged organic substrates such as aliphatic alcohols, free hydroxyl anomeric sugars, aromatic amines and C-protected α-aminoacids.
