Procedure: This example shows the preparation of a phosphinate compound, i.e., a compound having two P--C bonds. It also shows the use of a thiourea as a reactant. When equimolar quantities of bis(2-chloroethyl) methylphosphonite, p-chlorophenylacetaldehyde, and phenylthiourea are warmed at 90°-110° C for 1 hour, 2-chloroethyl [1-(3-phenylthioureido)-2-(p-chlorophenyl) ethyl]methylphosphinate is formed. Hydrolysis gives the corresponding phosphinic acid.

Procedure: To a solution of 5-cyclopropyl-8-methoxy-2,3,5,6-tetrahydrobenzo[b][1,5]diazocin-4(1H)-one (50.0 mg, 0.203 mmol) from Example 1 in dichloroethane (2 ml) at 0° C. was added acetic acid (0.035 ml, 0.609 mmol), 2-(4-chlorophenyl)acetaldehyde (47.0 mg, 0.304 mmol) prepared as above and sodium triacetoxyborohydride (129.0 mg, 0.609 mmol). The mixture was stirred overnight at room temperature and then sodium bicarbonate was added followed by extraction with dichloromethane. The organic phases were dried over sodium sulfate, filtered and concentrated. Preparative thin layer chromatography (pentane/ethyl acetate: 1/1) of the obtained residue gave the desired compound as a yellow oil (59 mg, 76%). followed by extraction with dichloromethane The organic phases were dried over sodium sulfate filtered concentrated

Procedure: To a solution of 2-(4-chlorophenyl)ethanol (2.00 g, 12.77 mmol) in dichloromethane (100 ml) was added Dess-Martin periodinane (8.12 g, 19.16 mmol) and the mixture was stirred at room temperature over weekend. Then was added diethylether (150 ml) and the resulting mixture was washed with a 1:1 solution (150 ml) of sodium carbonate (aqueous saturated) and sodium thiosulfate (aqueous saturated) and then with sodium bicarbonate (aqueous saturated) and finally with brine. The organic phase was then dried over sodium sulfate and evaporated. Silica gel flash chromatography (pentan/ethylacetate:9/1) afforded the desired compound (0.834 g, 42%) as a white solid. the resulting mixture was washed with a 1:1 solution (150 ml) of sodium carbonate (aqueous saturated) and sodium thiosulfate (aqueous saturated) The organic phase was then dried over sodium sulfate evaporated

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Dess-Martin periodinane (1.02 g, 2.4 mmol) was diluted in anhydrous CH2Cl2 (25 mL) under argon, and when solution was affected, 4-chlorophenethyl alcohol (33, 0.313 g, 2 mmol) was added dropwise. The mixture was stirred for 2 h and 15 min at room temperature, and was then quenched by addition of 20 mL sat. aq. Na2S2O3. After stirring at room temperature for 15 min, the layers were separated, and the aqueous layer was extracted with CH2Cl2 (2×50 mL). The organic layer was washed with H2O and sat. aq. NaCl (50 mL each) and was dried over anhydrous sodium sulfate and concentrated. The resulting semisolid residue was triturated with 10% EtOAc in hexanes, and the solid was filtered and discarded. The filtrate was concentrated, and the oily residue was purified by flash column chromatography (SiO2), eluting with a gradient of hexanes to 15% EtOAc in hexanes to afford the title compound as a clear yellow volatile oil (0.211 g, 88%). 1H-NMR (500 MHz; CDCl3): δ 9.75 (t, J=2.1 Hz, 1 H), 7.34 (d, J=8.3 Hz, 2 H), 7.15 (d, J=8.2 Hz, 2 H), 3.69 (d, J=2.0 Hz, 2 H). was then quenched by addition of 20 mL sat. aq. Na2S2O3 After stirring at room temperature for 15 min the layers were separated the aqueous layer was extracted with CH2Cl2 (2×50 mL) The organic layer was washed with H2O and sat. aq. NaCl (50 mL each) was dried over anhydrous sodium sulfate concentrated The resulting semisolid residue was triturated with 10% EtOAc in hexanes the solid was filtered The filtrate was concentrated the oily residue was purified by flash column chromatography (SiO2) eluting with a gradient of hexanes to 15% EtOAc in hexanes
