9-(3-methylbut-2-enyl)-9-borabicyclo[3.3.1]nonane

Conditions: temp:-78.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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
