Participants

Reaction Steps

Reflux dl-13-ethyl-3-methoxy-6-methylgona-2,5(10)-dien-17β-ol (5.5 g) in toluene (200 cc) and cyclohexanone (70 cc) with aluminum isopropoxide (4.0 g) for 2.5 hours. Add water and anhydrous sodium sulfate, filter and isolate the crude product. Triturate with ice cold methanol to obtain dl-13-ethyl-3-methoxy-6-methylgona-2,5(10)-dien-17-one (3.6 g), m.p. 118°-125°, λmax. KBr 5.78 μ, 5.90 μ, 6.0 μ. An analytical sample recrystallized from methanol has m.p. 163°-166°.
