Significance
The authors report an efficient route to a fluorene derivative with the 9,9′-positions functionalized with cholesterol’s carbon skeleton. Because attack of cholestanone with 2-biphenylmetal reagents was low-yielding, the authors chose to brominate and use a palladium-catalyzed Kumada coupling.
