The syntheses of linearly disposed progesterone and testosterone analogues are described. On the way of the syntheses, a plausible reaction path for the catalytic hydrogenation of the α, β-unsaturated ketone (11a) to the saturated ketone (20a) is discussed. The stereochemistry of the alumina catalysed condensation products of 3β, 20β-diacetoxy-8,9-seco-5α-pregnane-8,9,11-trione, not fully established in the previous paper, has been determined in the light of accumulated nulear magnetie rlsonanel (NMR) data.
