2,3,8a-trimethyl-3,4,4a,5,8,8a-hexahydro-1(2H)-naphthalenone → 2,3,8a-Trimethyloctahydronaphthalen-1(2H)-one

Participants

Reaction Steps

2,3,8a-trimethyl-3,4,4a,5,8,8a-hexahydro-1(2H)-naphthalenone (10 g, 52 mmol) was hydrogenated, at room temperature and atmospheric pressure, in ethyl acetate (100 ml) in presence of 5% Pd—C (1.0 g). The crude product was purified by bulb-to-bulb distillation (78° C./0.035 mbar) to give desired compound (9.88 g, 51 mmol, 98%) as a 3:2 mixture of diastereoisomers.
