*Procedure

To a stirred solution of ((3-((3aR,6aR)-2-hexyl-6a-(1-phenylvinyl)-3,3a,4,5,6,6a-hexahydropentalen-1-yl)benzyl)oxy)triisopropylsilane (0.48 g, 0.85 mmol, 1 equiv.) in THF (10 mL) was added slowly dropwise TBAF (1 M solution in THF, 1.02 mL, 1.02 mmol, 2 equiv.).  The reaction was stirred for 16 hours.

The reaction was diluted with diethyl ether (20 mL) and washed with water (20 mL).  The water layer was washed with diethyl ether (2 x 20 mL).  The diethyl ether layers were combined and washed with water (2 x 50 mL) and brine (50 mL) before being dried over magnesium sulphate, filtered and concentrated under reduced pressure. 

The product was purified by column chromatography (silica gel, 30 % diethyl ether in hexane) to yield the pure product as a yellow oil (0.22 g, 0.56 mmol, 66 %).  

*Yield (%) 66
*Type of Yield Isolated Product Yield
