60% | With pyridine; In N-methyl-acetamide; methanol; dichloromethane; | 1-Methyl, 8-tert-butyl 3-oxo-1,8-octanedioate A solution of <strong>[52221-07-5]mono-tert-butyl adipate</strong> (7.8 g, 37.5 mmol) in dichloromethane (175 ml) was treated with oxalyl chloride (9.8 ml, 112.5 mmol) followed by ten drops of dimethylformamide. The reaction was stirred at room temperature for 1 hour. The solvent was evaporated and the residue was dried under vacuum. To a solution of 2,2-dimethyl-1,3-dioxane-4,6-dione (5.42 g, 37.6 mmol) in dichloromethane (30 ml) at 0° C. was added pyridine (6.1 ml, 75 mmol) followed by the crude acid chloride in a solution of dichloromethane (30 ml). The reaction was stirred at 0° C. for 1 hour and at room temperature for 2 hours. The reaction was then washed with water and dried over anhydrous magnesium sulfate, filtered and concentrated. The crude residue was then dissolved in methanol and refluxed for 3 hours. The solvent was evaporated and the residue was purified by silica gel chromatography to give the title material (5.82 g, 60percent) as an oil. |

85% | With sodium hydroxide; In tetrahydrofuran; ethanol; | Mono-tert-butyl adipate A solution of methyl tert-butyl adipate (9.9 g, 45.8 mmol) in ethanol (70 ml) and tetrahydrofuran (70 ml) was stirred with aqueous sodium hydroxide (1N, 137 ml, 137 mmol) at 0° C. for 2 hours. The mixture was then diluted with water and washed with dichloromethane (2*). The mixture was diluted with dichloromethane and acidified with aqueous hydrochloric acid (1N, 150 ml). The organic layer was separated and the aqueous phase was extracted with dichloromethane. The combined organic layers were dried over anhydrous magnesium sulfate, filtered and concentrated to give the title material (7.82 g, 85percent). 1H NMR (C6D6, delta, ppm): 1.48 (9H, s, -OtBu), 1.52 (4H, m, -(CH2)2-), 2.05-2.10 (4H, m, 2*-CH2COO-). |
85% | Step 26-fert-Butoxy-6-oxohexanoic Acid.11CA solution of 11B (10.3 g, 47.6 mmol) and LiOH (1.26 g, 52.8 mmol) in 3:1 :1 MeOH/THF/hbO (50 mL) was stirred at room temperature for 16 h. The " reaction was diluted with EtOAc and washed with saturated aqueous Na2C03. The aqueous layer was separated and acidified with 1 N HCI, then extracted with EtOAc. The combined organics were washed with brine, dried (Na2S04), filtered and concentrated to yield 11 C (8.14 g, yield = 85percent): H NMR (300 MHz, CDCI3) delta 10.67 (br s, 1 H), 2.50-2.10 (m, 4H), 1.65 (m, 4H), 1.44 (s, 9H). |
