88.4% | With potassium hydroxide; In dimethyl sulfoxide; N,N-dimethyl-formamide; at 20℃; for 16h; | In a 1000ml round bottom flask,Add n-hexadecyl bromide (2) 97.5 g (0.32 mol, 1 eq), 1,3-propanediol (3) 73.5 g (0.96 mol, 3 eq),DMSO 200ml,DMF 200ml andPotassium hydroxide 72g (1.28mol, 4eq), stirred at room temperature16h.After completion of the reaction, 500 ml of water was added to the reaction solution, then the pH was adjusted to neutrality with a 5M hydrochloric acid solution, and the mixture was extracted with ethyl acetate (500 ml×2). The organic layers were combined and the organic layer was washed with saturated brine (500 ml×2). ), collecting organic phase,Dry with 10 g of anhydrous sodium sulfate, filter, and concentrate the filtrate under reduced pressure to obtain 102 g of a yellow solid.Recrystallization of petroleum ether yielded 85 g of white flake-like crystals with a yield of 88.4%. |
77% | General procedure: To a solution of 1,3-propanediol (19) (6.51 mL, 90 mmol) in dry DMF (40 mL) was added NaH (60% oil dispersion; 1.20 g, 30 mmol) in installments at 0 C and the mixture was stirred at room temperature for 10 min. Dodecyl bromide (4.80 mL, 20 mmol) and KI (3.32 g, 20 mmol) were added and the mixture was heated at 95 C for 4 h. After cooling, the mixture was poured into ice-water and extracted with AcOEt. The extracts were washed with brine, dried over Na2SO4 and evaporated. The resulting residue was purified by flash CC (silica gel; AcOEt/hexane, 1:2) to provide dodecyl ether 20a (3.38 g, 69%). Tetradecyl ether 20b (79%) and hexadecyl ether 20c (77%) were similarly prepared from 1,3-propanediol (19). | |
66.7% | With sodium hydroxide; In tetrahydrofuran; dimethyl sulfoxide; at 20℃; for 24h; | Add hexadecane bromide (1.52 g, 5 mmol) to the reaction flask.And 1,3-propanediol (1.14 g, 15 mmol),Add 5 ml of dimethyl sulfoxide and 5 ml of tetrahydrofuran to dissolve.Add sodium hydroxide (800mg, 20mmol)The reaction was carried out for 24 hours at room temperature.Dilute with 10 ml of water,Adjust the pH to neutral with 2M dilute hydrochloric acid,Extracted with ethyl acetate 3 times,Combine the organic phase,Washed with saturated brine and concentrated.Purified by silica gel column chromatography to give compound 1.0g, Yield: 66.7%. |

The reaction mixture was warmed up to 8O0C and stirred for overnight. After concentration, the residue was purified with a gradient mixture of chloroform, methanol, ammonia water and water (80:20:1 :1 to 100:40:3:3) by silica gel column chromatography to give 0.065g of product 16 (0.115 mmol, 27% yield); 1H NMR (MeOH-^) 58.21 (s, IH), 8.19 (s, IH) 5.84-5.74 (m, IH), 5.65-5.57 (m, IH), 4.92 (d, J = 7.0 Hz, 2H), 3.94 (q, J = 6.2 Hz, 2H), 3.52 (t, J = 6.2 Hz, 2H), 3.37 (t, J = 6.6 Hz, 2H), 2.58-2.44 (m, 2H), 1.90-1.78 (m, 2H), 1.74-1.62 (m, 2H), 1.54-1.43 (m, 2H), 1.36-1.14 (m, 12H), 0.89 (t, J = 7.0 Hz, 3H); 31P NMR (MeOH-^) 525.89; MS (ESI) m/z 566 (M+H)+, 564 (M-HV. |

With pyridine; triethylamine; In dichloromethane; at -30 - 0℃; | General procedure: 4.1. General method A Bis isopropyl phosphonoethoxyethylchloride (1) (2.58 g,10.0 mmol) or bis isopropyl phosphonomethyltosylate (7) (3.50 g,10.0 mmol) in anhydrous acetonitrile (130 ml) was treated withbromotrimethylsilane (13 ml) overnight at room temperature.The mixture was then evaporated and codistilled with acetonitrile (3x25 mL), water (2x25 ml), ethanol (25 mL) and toluene (3 x 25 mL). The syrupy residue was dissolved in dichloromethane (50 ml) then DMF (0.1 ml) and oxalyl chloride (6.0 ml, 68.8 mmol) were added. The solution was gently refluxed (2 h), evaporated to dryness, and redissolved in dichloromethane (20 ml). The solution was cooled down to 0 C and treated slowly with pyridine (1.6 ml).The mixture was added to a cooled ( 30 C) solution of hexadecyloxypropanol (6.01 g, 20 mmol) in dichloromethane (100 ml) and triethylamine (8.7 ml). The mixture was allowed to reach 0C and kept at this temperature for3 h.The reactionmixturewas evaporated,codistilled with toluene (3 50 ml) and the residue was chromatographed on a silica gel column (400 g) in EtOAc/hexane (1:2/1:1). 4.1.2. Bis(hexadecyloxypropyl)phosphonomethyltosylate (8)Prepared similarly according to the published procedure [12]. Yield 6.94 g of syrup (83%). Identity was verified using authentic sample on TLC, Rf w0.3 (30% EtOAc/hexane). |
