diethyl benzylphosphonate Chemical Properties,Uses,Production
Chemical Properties
CLEAR COLOURLESS TO SLIGHTLY YELLOW LIQUID
Uses
Diethyl benzylphosphonate is used as a reactant for synthesis of 3,5-dihydroxy-4-isopropylstilbene for treatment of skin disorders and natural cytotoxic marine products of polyketide origin via intramolecular Diels-Alder reactions. It is also used as reactant for cyclization of aryl ethers, amines and amides & for investigating the effects of functional groups on the performance of clue organic LEDs.
Uses
Reactant for synthesis of:
3,5-dihydroxy-4-isopropylstilbene for treatment of skin disorders
Natural cytotoxic marine products of polyketide origin via intramolecular Diels-Alder reactions
Stilbenes via on-column oxidation of vicinal diols and Horner-Emmons reactions
Inhibitors of teh Wnt pathway for colon cancer repression using Wadsworth-Emmons reactions
Antimalarial drug analogs against P. falciparum
Reactant for:
Cyclization of aryl ethers, amines, and amides
Investigating the effects of functional groups on the performance of clue organic LEDs
Preparation
Diethyl benzylphosphonate was synthesized according to the previously published procedure [1]. Benzylphosphonic acid (1 mmol, 172 mg) and triethyl orthoacetate (30 mmol, 5.5 mL) were mixed overnight at 90 °C. The completion of the reaction was monitored by 31P NMR. After the completion of the reaction, an excess of the orthoester was evaporated under reduced pressure. The crude product was purified via a short silica gel column (hexanes/ethyl acetate). The compound 1 was isolated as a transparent oil with 98% yield (0.98 mmol, 224 mg). 1H NMR (400 MHz, DMSO-d6) δ 7.39–7.14 (m, 5H), 3.94 (dq, JH-P = 7.9, JH-H = 7.0, 4H), 3.21 (d, JH-P = 21.6 Hz, 2H), 1.16 (t, JH-H = 7.0 Hz, 6H); 13C NMR (101 MHz, DMSO-d6) δ 132.3 (d, JC-P = 9.0 Hz), 129.7 (d, JC-P = 6.6 Hz), 128.2 (d, JC-P = 3.0 Hz), 126.4 (d, JC-P = 3.4 Hz), 61.3 (d, JC-P = 6.5 Hz), 32.3 (d, JC-P = 135.1 Hz), 16.1 (d, JC-P = 5.8 Hz); 31P NMR (162 MHz, DMSO-d6) δ 26.5. The NMR data are in accordance with those reported in literature [2].
