Procedure

To a solution of 50 mg of acetic acid (1R,3R)-3-acetoxy-5-[(2E,9Z)-12,12,12-trifluoro-7,7-dimethyl-11-triethylsilanyloxy-11-trifluoromethyl-dodeca-2,9-dienylidene]-cyclohexyl ester in 1.5 ml of CH3 1OH was added at 22° a solution of 37 mg of K2CO3 in 0.25 ml of water and stirring, was continued for 8 h after which time t.l.c. indicated completion of the reaction. The mixture was evaporated and the residue was partitioned between dichloromethane and aqueous sat. NaCl, the organic layer was dried over MgSO4 and evaporated. The residue was chromatographed on silica with hexane/AcOEt 2:1 to give 34 mg of the pure (t.l.c.) title compound as a colorless resin. IR (neat): 3345s (OH), 1661 w and 1622 w (C═C); MS (EI): 444/10 (M), 426/8 (M—H2O).
