Abstract
The hexamethyltriamide of phosphorous acid activated by the addition of iodine at the optimum molar ratio 1.05∶0.05 was used as a phosphorylating reagent to synthesize cholecalciferyl-3-0-(N,N-dimethylamido)thiophosphate derivatives of 1,3-benzylidene-rac-glycerol, 1,2-isopropylidene-rac-glycerol, 1,3-dioleoyl-rac-glycerol, and 1,2-dioleoyl-rac-glycerol in a one-pot procedure in high overall yields (81–86%). The compounds represent new model types of phospholipid structures which, in addition to glycerol and a steroid fragment, contain a biologically important linkage other than an oxygen-phosphorus bond.
