Reaction Steps
A racemic mixture of (1R,3R,4R)-benzyl 3-hydroxy-4-methylcyclopentanecarboxylate and (1S,3S,4S)-benzyl 3-hydroxy-4-methylcyclopentanecarboxylate (217 mg, 0.463 mmol) and palladium hydroxide on carbon (65.0 mg, 0.463 mmol) in methanol (10 mL) was degassed under vacuum/nitrogen, and the mixture was hydrogenated overnight at 50 psi. The catalyst was removed by filtration and rinsed with methanol. The filtrates were combined and concentrated in-vacuo to yield a racemic mixture of (1R,3R,4R)-3-hydroxy-4-methylcyclopentanecarboxylic acid and (1S,3S,4S)-3-hydroxy-4-methylcyclopentanecarboxylic acid (131 mg, 0.454 mmol, 98% yield) as a colorless oil which solidified upon standing overnight.
