Procedure
To a solution of 4-[1-Furan-3-yl-meth-(E)-ylidene]-2-(2,4,6-trimethyl-phenyl)-cyclopentane-1,3-dione (167 mg) in ethanol (5 ml) is added 5% palladium on charcoal (15 mg) and the resulting suspension stirred under an atmosphere of hydrogen (3 bar) for 5 hours. The reaction is filtered through a pad of Celite, washed with methanol and the filtrate purified by automated flash chromatography to give 4-furan-3-ylmethyl-2-(2,4,6-trimethyl-phenyl)-cyclopentane-1,3-dione.
