Versuchsvorschrift

To a solution of 2-[(2S)-2-(3,4-dichlorophenyl)pent-4-enyl]-1-oxo-1,2,3,4-tetrahydronaphtho[1,2-f][1,4]thiazepine-6-carbonitrile (Example 1, 225 mg, 0.50 mmol) in 3:1 THF/water (10 mL) under nitrogen at 0° C. was added osmium tetroxide (4% in water, 32.5 μL, 0.01 mmol) followed in 10 min by portion wise addition of sodium periodate over 5 min. The reaction mixture was allowed to warm to ambient temperature over 3 h and clarified by the addition of water. The products were extracted into ether and organic layer was washed with saturated NaHCO3 and brine, dried (Na2SO4), and evaporated to 230 mg of an oil which was chromatographed on silica gel in 10% MeOH/CHCl3 to give 40 mg of intermediate 78a, 22 mg of Intermediate 78b and 11 mg of Intermediate 78c.
