|---|---|---|---|
| 反応物 | 1,1'-Biphenyl, mixt. with 1,1'-oxybis(benzene) | HCID 24670 | — |
| 反応物 | 3beta-Acetoxy-16alpha-chloro-5-pregnen-20-one | HCID 22213258 | — |
| 生成物 | Dehydropregnenolone acetate | HCID 92855 | 56% |
反応手順
One gram of 3β-acetoxy-16α-chloro-5-pregnen-20-one is treated analogously to Example 1 in "Dowtherm" for 6 hours at 240° C. and worked up. Recrystallization from isopropyl ether yields 400 mg of 3β-acetoxy-5,16-pregnadien-20-one (56% of theory).
