Versuchsvorschrift

To the THF (1 ml) solution of 6,6-dimethyl-11-oxo-8-vinyl-6,11-dihydro-5H-benzo[b]carbazole-3-carbonitrile (Compound B2-24, 20 mg, 0.064 mmol), t-butanol solution of osmium tetraoxide (19 μl, 0.3 eq.) and 50% aqueous solution of N-methylmorpholine-N-oxide (30 μl, 2.0 eq.) were added and the mixture was stirred at room temperature for 3 hr. To the reaction solution, 10% aqueous solution of disodium ethylenediamine tetraacetic acid was added, followed by extraction with ethyl acetate. The organic layer was dried over sodium sulfate. The drying agent was removed by filtration and the residues obtained after concentration under reduced pressure were purified by high performance liquid chromatography to obtain the title compound (21 mg, 63%).
