Procedure
To a round-bottomed flask (500 mL) containing trans tert-butyl(6-(2,4,5-trifluorophenyl)-3-[(triisopropylsilyl)oxy]cyclohex-2-en-1-yl)carbamate (10.7 g) dissolved in tetrahydrofuran (100 mL), tetrabutylammonium fluoride (1M in tetrahydrofuran, 26 mL) was added and the mixture was stirred for 1 h. The solution was concentrated to a dark brown oil and purified by chromatography (silica gel, gradient 20%-40% ethyl acetate in hexane) to yield the product as a mixture of enantiomers. HPLC using a chiral AD column (12% isopropanol in heptane) gave the title compound as the slower eluting isomer. LC/MS 227.1 (M+1).
