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 gof palladium at 10% over charcoal. After filtration and evaporation of the volatile portions, a residue was obtained which by fractional distillationgave 1.77 g (89%), of the desired dione; B.p. 80°/0.001 Torr;
