实验步骤: A stirred solution of 5-phenylpentanal (9.96 g, Reference Example 6) in anhydrous tetrahydrofuran (100 ml) at room temperature was treated with (tert-butoxycarbonylmethylene)triphenylphosphorane (27.5 g). The resulting orange solution was stirred for 2.5 hours then evaporated. The residual crude product was subjected to flash chromatography on silica eluting with a mixture of hexane and ethyl acetate (19:1, v/v) to afford the title compound (12.4 g) as a colourless oil. NMR (CDCl3): δ1.45 (s,9H), 1.65 (m,4H), 2.18 (q,2H), 2.61 (t,2H), 5.70 (d,1H), 6.82 (dt,1H), 7.10-7.30 (m,5H). then evaporated The residual crude product was subjected to flash chromatography on silica eluting with a mixture of hexane and ethyl acetate (19:1

实验步骤: Using a similar procedure to that described in Example 12, part c, except starting from methyl 4-(5-formyl-1-propylindol-3-ylmethyl)-3-methoxybenzoate, and using tert-butyl (triphenylphosphoranylidene)acetate, methyl E-4-[5-[2-(t-butoxycarbonyl)vinyl]-1-propylindol-3-ylmethyl]-3-methoxybenzoate was obtained (98%) as a viscous oil; partial NMR (250 MHz, DMSO-d6): 0.81(t, 3H, CH2CH3), 1.48(s, 9H, C(CH3), 1.75(m, 2H, CH2CH3, 3.82(s, 3H, OCH3), 3.91(s, 3H, OCH3), 6.38(d, J=15.8 Hz, 1H, CH=CH), 7.6(d, J=15.8 Hz, 1H, CH=CH).
