m-Chloroperbenzoic acid → HCID 19800988, compound

Participants

Reaction Steps

In dichloromethane (2 ml) was dissolved 4-O-(chloroacetylcarbamoyl)-2-(1,2-epoxy-1,5-dimethyl-4-h-exenyl)-3-methoxy-1-phenylthiomethyl-1,4-cyclohexanediol (200 mg). To the solution was added, under ice-cooling, m-chloroperbenzoic acid (80.9 mg), and the mixture was stirred for 30 minutes. The reaction mixture was diluted with ethyl acetate (70 ml), which was washed with a saturated aqueous solution of sodium hydrogencarbonate and a saturated aqueous saline solution, followed by drying over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure. The residue was then purified by means of a silica gel column chromatography (carrier 10 g, developing solvent: ethyl acetate - hexane=1:2) to afford 4-O-(chloroacetylcarbamoyl)-2-(1,2-epoxy-1,5-dimethyl-4-hexenyl)-3-methoxy-1-phenylsulfinylmethyl-1,4-cyclohexanediol (175 mg: yield 85%) as colorless powder.
