99% | Stage #1: With 1,1'-carbonyldiimidazole In dichloromethane at 0 - 20℃; for 4 h; |
To a solution of 1.1 (10 g, 89 mmol) in DCM (100 mL) at 0° C. under N2 atmosphere was added 1,1-carbonyldiimidazole (43 g, 267 mmol). The mixture was stirred at room temperature for 4 hours, then MeOH (100 mL) was added. The mixture was allowed to stir overnight. The solvent was evaporated at low temperature to afford 2 (11.2 g, 99percent). |

Synth. 75, PL95-200, 1998) (31.5 g, 281 mmol) in anhydrous N, N-DIMETHYLFORMAMIDE (300 mL), under an atmosphere of nitrogen, was added potassium carbonate (97 g, 703 mmol), and iodomethane (35 mL, 563 mmol). The resulting mixture was stirred at room temperature for 16 hours, then poured into water (1 litre), and extracted with diethyl ether (3 x 400 mL). The combined diethyl ether layers were washed with water (3 x 500 mL), saturated NACL (200 mL), dried over MGS04, filtered and concentrated I71 VACUO, to give 34 g (96 percent) of crude product.

85% | With lithium aluminium tetrahydride In tetrahydrofuran at -78℃; for 7 h; | (a) cyclopent-3-enylmethanol (0164) (0165) To a suspension of lithium aluminum hydride (0.5083 g, 13.37 mmol, 3eq) in dry 100 ml THF at −78° C., cyclopent-3-enecarboxylic acid (0.5000 g, 4.45 mmol) was added drop wise over 1 h. The mixture was stirred for 6 h, and then quenched with 15 ml 1M NaOH. Mixture was stirred for an additional 2 h, then concentrated and up taken in diethyl ether and dried over MgSO4 to afford clear liquid (3.79 mmol, MW 98.14 g/mol, 85percent).1H NMR (300 MHz, CDCl3): δ 2.12-2.16; (ttt 1H), 2.49-2.53; (dd, 2H), 3.57-3.58 (d, 3H, 5.14 Hz), 5.69; (s, 2H). |
