实验步骤: A solution of tryptamine (3.04 g, 19.0 mmol) and phthalic anhydride (3.0 g, 20.0 mmol) in toluene (300 ml) was boiled under reflux for 12 h using a water separator. The solvent was removed i. vac. and the residue was recrystallized from methylene chloride/cyclohexane. Yield: 4.46 g (81%) under reflux for 12 h The solvent was removed i and the residue was recrystallized from methylene chloride/cyclohexane

实验步骤: Tryptamine (3.04 g, 19.0 mmol) and phthalic anhydride (3.00 g, 20.0 mmol) were boiled for 12 h in a water separator. The solvent was distilled off i. vac. and the residue was dissolved in methylene chloride. Product was precipitated out by addition of cyclohexane and the precipitate was filtered off with suction and dried. Yield: 4.46 g (Ind-1; 87%) The solvent was distilled off i and the residue was dissolved in methylene chloride Product was precipitated out by addition of cyclohexane the precipitate was filtered off with suction dried

实验步骤: To a solution of 2-[2-(1H-indol-3-yl)-ethyl]-1H-isoindole-1,3(2H)dione (3.77 g, 13.0 mmol) in dry THF (0.13 L) under argon was added NEt3 (1.84 mL, 13.0 mmol). This mixture was cooled to −78° C., and neat t-BuOCl (1.54 mL, 13.0 mmol) was added. The reaction mixture was stirred for 30 min at −78° C. A solution of 9-(3-methyl-2-butenyl)9-bora-bicyclo[3.3.1]nonane (40 mmol) in hexanes was added. The reaction mixture was stirred for 6 h at −78° C. It was quenched with 1 M aq HCl, and permitted to warm to rt overnight. The reaction mixture was extracted with CH2Cl2. The CH2Cl2 extracts were dried, filtered, and concentrated to give an oil. The oil was purified by silica chromatography to give the title compound: TLC Rf=0.36 (CH2Cl2); MS (ESI+) m/z 381.2, 359.2; 1H NMR (300 MHz, CDCl3) δ 7.91 (1H), 7.88-7.69 (5H), 7.29 (1H), 7.10 (2H), 6.18 (1H), 5.25 (2H), 3.95 (2H), 3.16 (2H), 1.61 (6H). The reaction mixture was stirred for 6 h at −78° C It was quenched with 1 M aq HCl to warm to rt overnight The reaction mixture was extracted with CH2Cl2 The CH2Cl2 extracts were dried filtered concentrated to give an oil The oil was purified by silica chromatography
