Answer
![(1aR,1bR,3S,5aR,5bS,7aS,8aS,9aS,9bS,9cR,9dR)-1b,3-Dihydroxy-5a,7a-dimethyloctadecahydro-8H-cyclopropa[4,5]cyclopenta[1,2-a]cyclopropa[l]phenanthren-8-one](https://static.chemtradehub.com/structs/825/82543-16-6-fbb4.webp "(1aR,1bR,3S,5aR,5bS,7aS,8aS,9aS,9bS,9cR,9dR)-1b,3-Dihydroxy-5a,7a-dimethyloctadecahydro-8H-cyclopropa[4,5]cyclopenta[1,2-a]cyclopropa[l]phenanthren-8-one")
This compound is synthesized through a multi-step process involving ring-closing metathesis and subsequent functionalization. The synthesis typically requires the use of Grubbs catalysts and involves the selective introduction of hydroxyl and methoxy functionalities. The overall yield is moderate, with careful control of reaction conditions to achieve high purity.
