Reaction Steps

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 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; B.p. 80°/0.001 Torr; d420 = 0.9292; nD20 = 1.4501
