Procedure

1.96 g (10 mM) of 5-isopropyl-non-3-ene-2,8-dione, prepared according to the method described in paragraph (a) of example 2, in 20 ml of ethyl acetate were reduced by catalytic hydrogenation in the presence of 0.196 g of palladium at 10% over charcoal. After filtration and evaporation of the volatile portions, a residue was obtained which by fractional distillation gave 1.77 g (89%), of the desired dione;
