Procedure

tert-Butyl(1S,2S,5S)-7-oxo-6-oxabicyclo(3,2,1)octane-2-carboxylate was dissolved in THF—H2O. At 0° C., LiOH (3 eq.) was added and the resulting mixture was stirred at 0° C. for 2 hours. TLC showed starting material was consumed. The mixture was then acidified to pH of about 2. The product was extracted with EtOAc (×3). The combined extracts were washed with brine (×1); dried over MgSO4. After filtration, the filtrate was concentrated to give (1S,2S,5S)-2-(tert-butoxycarbonyl)-5-hydroxycyclohexanecarboxylic acid (quantitative).
