Illudin M → Dehydroilludin M

Participants

Reaction Steps

A mixture of illudin M (200 mg) and pyridinium dichromate (1 g) in dry dichloromethane (60 ml) was stirred at room temperature in a flask equipped with a rubber septum so that an atmosphere of argon could be maintained. After 20 hours, the reaction mixture was diluted with diethyl ether (20 ml) and filtered through a short column of silica gel. The column was further eluted with more diethyl ether and the combined filtrate was concentrated, giving a residue which was chromatographed on silica gel with hexane-ethyl acetate (10:1 ) as eluent. The desired compound was obtained in early fractions from the chromatography. The yield was 140 mg of white crystals melting at 64°-65° C.
