Answer
![(R)-Methyl 4-((3R,5S,8R,9S,10S,13R,14S,17R)-3-hydroxy-10,13-dimethyl-7-oxohexadecahydro-1H-cyclopenta[a]phenanthren-17-yl)pentanoate](https://static.chemtradehub.com/structs/105/10538-59-7-8692.webp "(R)-Methyl 4-((3R,5S,8R,9S,10S,13R,14S,17R)-3-hydroxy-10,13-dimethyl-7-oxohexadecahydro-1H-cyclopenta[a]phenanthren-17-yl)pentanoate")
The compound is synthesized via a multi-step process involving protection of the phenanthrene ring, esterification, and ring-opening of the cyclohexene oxide. Commonly used catalysts include acid or base conditions, and the yield and selectivity can be optimized with careful control of reaction conditions.
