Participants

Reaction Steps

A mixture of 3.9 g of (1R,6S,7S)-8,8-dichlorobicyclo [4.2.0]oct-2-en-7-ol, prepared as shown in Example 1, 9.0 g of pyridinium chlorochromate and 14 g of magnesium sulfate in 200 ml of methylene chloride under nitrogen was refluxed for 4 hours. The mixture was cooled, filtered first through celite then Florisil. Solvent was removed from the eluate under reduced pressure and the residue distilled under vacuum to give 3.1 g of (1R,6S)-8,8-dichlorobicyclo[4.2.0]oct-2-en-7-one, [α]D =+71.4°, (C=0.7, CHCl3).
