实验步骤: 7-fluoro-2,3-dihydro-1,5-benzothiazepin-4(5H)-one (76 mg, 0.38 mmol) dissolved in toluene (1 mL) and cooled to 0° C. in an ice bath. Red-Al (275 mL, 0.91 mmol) was added and then the reaction allowed to warm to room temperature. The reaction was heated at reflux for 1.5 hours. 1 N sodium hydoxide was added slowly until pH >10, this was stirred for 10 minutes, extracted with dichloromethane (3×25 mL), washed with water, and dried (sodium sulfate). The concentrated organics were purified by preparative thin layer chromatography on silica gel and eluted with 50% ethyl acetate in hexanes to give 7-fluoro-2,3,4,5-tetrahydro-1,5-benzothiazepine (30.8 mg, 93%). 1H NMR (CDCl3, 300 MHz): δ 7.32 (t, 1H, J=7.5 Hz), 6.53–6.42 (m, 2H), 4.09 (s-broad, 1H), 3.31–3.27 (m, 2H), 2.83–2.79 (m, 2H), 2.11–2.04 (m, 2H) ppm. to warm to room temperature The reaction was heated at reflux for 1.5 hours extracted with dichloromethane (3×25 mL) washed with water dried (sodium sulfate) The concentrated organics were purified by preparative thin layer chromatography on silica gel eluted with 50% ethyl acetate in hexanes

实验步骤: 6-fluoro-2,3-dihydro-4H-1-benzothiopyran-4-one (100 mg, 0.54 mmol) was dissolved in acetic acid (0.5 mL, 1.1 eq), sodium azide (71.2 mg, 1.1 mmol) was added and mixture was heated to 50° C. Sulfuric acid (0.13 mL, 4.3 eq) was added slowly and stirred at 50° C. for 1.5 hours. Ice chips (150 mg) were added and a green solid precipitated, this was filtered, washed with water and dried to give 7-fluoro-2,3-dihydro-1,5-benzothiazepin-4(5H)-one (80 mg, 24%). 1H NMR (CDCl3, 300 MHz): δ 7.77 (s-broad, 1H), 7.69 (t, 1H, J=7.3 Hz), 6.94–6.82 (m, 2H), 3.42 (t, 2H, J=7 Hz), 2.63 (t, 2H, J=6.7 Hz) ppm.
