Participants

Reaction Steps

To a stirred solution of the above diene (31) in THF (250 mL) was added in one portion N-(benzyloxycarbonyloxy) -succinimide (40 g) (slightly exothermic) followed by after 15 min triethylamine (23 mL). The reaction was stirred for 16 h at room temperature, evaporated, taken up in ethyl acetate, washed with 1N Na2CO3, saturated NaCl, dried over MgSO4 and evaporated to give crude product (32). TLC Rf 0.26 (10% ethyl acetate, n-hexane); 1H NMR (CDCl3) δ1.24 (3H, d, J=7 Hz), 2.73(4H, br s), 3.55(3H, s), 4.27(1H, q), 4.64(1H, br s), 4.78(1H, br d), 5.12(2H, s), 5.64(1H, br s), 7.38 (5H, s).
