Versuchsvorschrift
To a solution of (S)-1-((S)-1-(4-bromophenyl)ethyl)-4-(2-methylallyl)-4-phenyl-1,3-diazepan-2-one (23 mg, 0.054 mmol) in 2:1 i-Propanol/CH2Cl2 (2 mL) was added the cobalt catalyst A, prepared as described below, (c.a. 1 mg, cat. amount) and phenylsilane (250 μL, excess). The mixture was stirred vigorously in open air for 1 h. LC-MS found the reaction completed. The mixture was quenched with 1% aq HCl, concentrated and purified by prep HPLC to afford the title compound (9.1 mg, 38%). LC-MS Method 1 tR=2.12 min., m/z 445, 447(M+1); 1H NMR (CDCl3) δ 7.48 (d, 2H), 7.37-7.22 (m, 5H), 6.97 (d, 2H), 5.52 (q, 1H), 2.84 (td, 1H), 2.65 (dt, 1H), 2.28-2.07 (m, 3H), 1.89 (d, 1H), 1.45 (d, 3H), 1.21 (s, 3H), 1.07 (m, 1H), 0.62 (s, 3H).
