Reaction Steps
Prepared from 1-methylindoline (1j, 13.5 mg, 0.100 mmol, 1.00 equiv), catBH (24.0 mg, 0.200 mmol, 2.00 equiv), norbornadiene (9.2 mg, 0.10 mmol, 1.00 equiv) and B(C6F5)3 (5.1 mg, 0.010 mmol, 0.10 equiv) according to GP 3. The title compound was purified by flash column chromatography using cyclohexane/EtOAc/Et3N (30/1/1) as eluent to afford 3j (7.5 mg, 30%) as a white solid.
