実験手順

The silylated alkene 5b (1.18 g, 2.6 mmol) was dissolved in 10 ml of THF. n-Bu4NF.3H2O (0.94 g, 3.0 mmol) was added and the yellow solution stirred for 30 min. The solution was then diluted with Et2O (100 mL), washed with H2O (200 mL), and the organic layer was concentrated. Recrystallization from ethyl acetate gave 0.48 g (1.5 mmol, 57.7%) of 5a as a white solid: 235°-240° C. (dec); 1H NMR (CDCl3) delta 1.873 (2, 10H), 1.992 (s, 2H), 3.472 (s, 1H), 3.529 (s, 1H), 6.70-6.76 (m, 2H), 6.96-7.04 (m, 2H), 7.06-7.14 (m, 2H), 7.21-7.29 (m, 2H); HRMS calc. 330.1621, found 330.1617; MS m/e (rel. intensity) 330 (100), 329 (43), 273 (37), 235 (16), 197 (11), 142 (65).
