Yield	Reaction Conditions	Operation in experiment
79.4%	With phosphoric acid; triethylamine; trichloroacetonitrile; at 0 - 20℃; for 3h;	General procedure: To a dry round bottom flask was added alcohol (6.0 equiv.), crystalline phosphoric acid (1.0 equiv.) and triethylamine (4.5 equiv.), and then was added trichloroacetonitrile (5.0 equiv.) dropwise at 0 C after the acid was dissolved by stirring. The reaction was then stirred at room temperature for 3 h, followed by addition of water to the reaction mixture. The solution was then extracted three times with ethyl ether, and the water layer was cooled in an ice bath and cyclohexylamine (10.0 equiv.) was added. The product was precipitated by adding acetone.
59%		General procedure: To a solution of the alcohol (1 mmol) in acetonitrile (1 mL), trichloroacetonitrile (2.4 mmol) is added, followed by dropwise addition of tetrabutylammonium dihydrogenphosphate (2.0 mmol) in acetonitrile (5 mL). The reaction mixture is stirred at room temperature for two hours, or until all the starting material is consumed. The solvent is removed in vacuo and the crude material is pre-purified by flash chromatography on silica gel (isopropanol/conc. aq NH4OH/H2O 7:2:1). The column fractions which show the presence of phosphate on TLC (e.g., with molybdate reagent) are combined and concentrated under reduced pressure. A Dowex 50WX8 ion-exchange column of 8 cm tall and 1 cm diameter is loaded and equilibrated with a mixture of conc. NH4OH/H2O 3:1 and afterward flushed with a buffer solution of 0.025 M NH4HCO3 until the pH reaches 8.0. The silica column residue is percolated through the DOWEX column with the same NH4OH buffer, collected, and dried either by lyophilization or by evaporation under reduced pressure until excess ammonium hydrogen carbonate is evaporated. The residual ammonium organophosphates are isolated as white solids

Yield	Reaction Conditions	Operation in experiment
	With silver carbonate; In toluene; at 95℃; for 16h;	Step B: Benzyl di(octyloxycarbonyloxy-1-ethyl)phosphate (36); Chloroethyl octyloxyformate (35) (3.73 g) was added to a suspension of <strong>[1623-07-0]benzyl phosphate</strong> (1.45 g) and silver carbonate (6 g) in toluene and the mixture stirred at 95 C. for 16 hours. The suspension was filtered to remove the solid. After concentration under reduced pressure, the filtrate was purified using chromatography (silica gel, 20% ethyl acetate in hexane) to provide 1.75 g of the title compound (36) as a colorless oil.

Yield	Reaction Conditions	Operation in experiment
82%		Step B: Benzyl Diphenylpropylcarbonyloxymethyl Phosphate (28); A solution of 1.8 g of benzylphosphoric acid in 90 mL of MeOH and 30 mL of water was treated with Dowex 50WX2-400 (153 mL) at room temperature for 2 hours. The resin was removed by filtration using a glass filter and 2.5 g of silver carbonate powder was added to the filtrate. After the resulting suspension was heated at 80 C. for 1 hour, all solvent was removed under reduced pressure to dryness. 300 mL of dry toluene was added to the silver salt followed by the addition of phenylpropylcarbamoyloxymethyl chloride and the suspension was heated at 100 C. overnight. After the solid was removed by filtration, the product was purified by silica gel chromatography using hexane/ethylacetate (3:1) as the eluent to provide benzyl diphenylpropylcarbonyloxymethyl phosphate (28) as a colorless liquid (2 g, 82%). 1H NMR (CDCl3, 400 MHz): δ 7.10-7.38 (m, 15H), 5.56-5.64 (m, 4H), 5.08 (d, 2H, J=8.0 Hz), 2.61 (t, 4H, J=8.0 Hz), 2.32(t, 4H, J=8.0 Hz), 1.92 (q, 4H, J=8.0 Hz).
