Procedure:
The procedure of Ercoli and Ruggieri (Gazz. Chim. Ital. 84, 312, 1954, incorporated herein by reference) was followed to prepare 20-cyano-20-hydroxy-4-pregnene-3-one (I-25) from progesterone. Thus, the suspension of progesterone 1.2 g in acetone cyanohydrin 2.4 ml was stirred and warmed at 40° C. until all the progesterone was dissolved. Four drops of triethylamine was then added. After 2 h the precipitate was filtered and dried to give crude I-25 1.4 g; m.p. 188°-90° C. After recrystallization from ethanol (contained 1% acetic acid), the product was obtained as fine crystals, m.p. 199°-200° C. The mixture containing cyanohydrin (I-25) 0.4 g, methane sulfonyl chloride 1 ml and pyridine 5 ml was stirred at room temperature for 5 h, then at 80° C. for 1 h. Water 20 ml was added and the precipitate was collected. The crude product was chromatographed on silica gel TLC plate (developed by hexane:/ethyl acetate, 1:1). The yield of I-26 was 80 mg, m.p. 195°-6° C.

Procedure:
Carbon tetrabromide (49.2 g, 0.15 mol) in methylene chloride (150 mL) was added at 0° C. to a stirred solution of triphenyl phosphine (78.2 g, 0.30 mol) in methylene chloride (600 mL) under nitrogen. The solution was stirred at 0° C. for 1 hr. and (R)-t-butyl 2-formyl-1-pyrrolidinecarboxylate (21.9 g, 0.10 mol) was added. After 30 min. a solution of sodium carbonate (75 g, 0.75 mol) in water (300 mL) was added. The phases were separated and the aqueous phase was reextracted with methylene chloride (200 mL). The organic phase was washed with water (40 mL), and the majority of solvent was removed under reduced pressure leaving the material in a minimum of methylene chloride. Ethyl acetate (500 mL) was added and the resulting precipitate of triphenylphosphine oxide was filtered off. The mother liquors were evaporated and filtered repeatedly to remove additional triphenylphosphine oxide. The residual solid in ethyl acetate was then concentrated and applied to a silica gel column. Elution with ethyl acetate:Skellysolve B (1:10) gave 31.6 g (91%) of product. This was crystallized from petroleum ether to give 25.8 g of product, m.p. 64°-67° C. The analytical sample was recrystallized from ethyl acetate:Skellysolve B. [α]D -21° (c 0.81, MeOH).
