実験手順

To a solution of 360 mg (8S,8aR)-3,4,6,7,8,8a-hexahydro-2H-chromen-8-ylmethanol added 2.2 mL DMF, then 224 mg imidazole followed by 0.66 mL tert-butyl(chloro)diphenylsilane. The reaction was stirred overnight at RT, then added to water and extracted with diethyl ether. The crude extract was dried over Na2SO4, filtered, concentrated, then purified on silica gel to provide the title compound. 1H NMR (500 MHz, CDCl3) δ=1.05 (s, 9H), 1.37-1.46 (m, 1H), 1.54-1.58 (m, 1H), 1.63-1.73 (m, 2H), 1.86-2.09 (m, 3H), 2.16-2.24 (m, 1H), 2.25-2.31 (m, 1H), 3.53 (m, 1H), 3.60 (dd, J1=9.8 Hz, J2=7.7 Hz, 1H), 3.80 (d, J=5.1 Hz, 1H), 3.90 (dd, 10.0 Hz, J2=7.4 Hz, 1H), 3.94-3.98 (m, 1H), 4.49-5.52 (m, 1H), 7.35-7.42 (m, 6H), 7.67-7.72 (m, 4H) ppm.
