Abstract

Cholestane derivative (IIb) having a bridged 3-azabicyclo [3. 3. 1] nonane ring system was synthesized from 3-oxo-5α-cholestane-5-carbonitrile (III) by a six-step reaction sequence. The over-all yield was very high indicating high stereospecificity or uniformity of the reaction used. Reduction of 3α-formyl-3β-methyl-5α-cholestane-5-carbonitrile (VIII) to the amino alcohol (Xa) was effected by means of lithium aluminum hydride reduction in the presence of aluminum chloride.
