100% | With ethyl acetate; for 0.0333333h; | General procedure: A mixture of the appropriate diene (1 mmol), dienophile (1mmol), and EtOAc (2-3 drops) was subjected to hand grindingwith a pestle in a mortar for the time shown in Tables 1 and 2. Almost immediately, the color of the mixture changed from fluorescent-green or yellow to white. The EtOAc was removed undervacuum to afford the pure solid product in quantitative yield. 2-(4-Bromophenyl)-4,9-diphenyl-3a,4,9,9a-tetrahydro-1H-4,9-epoxybenzo[f]isoindole-1,3-dione (5b)White solid; yield: 521 mg (quant); mp 242 C. 1H NMR (500MHz, CDCl3): δ = 8.05 (d, J = 7.5 Hz, 4 H), 7.54 (t, J = 7.5 Hz, 4 H),7.47 (d, J = 7.0 Hz, 2 H), 7.28-7.22 (m, 4 H), 7.05 (dd, J = 3.0, 5.0Hz, 2 H), 6.43 (d, J = 8.5 Hz, 2 H), 4.26 (s, 2 H). 13C NMR (125MHz, CDCl3): δ = 173.0, 144.0, 136.2, 132.1, 130.1, 128.8, 128.7,128.3, 127.9, 127.1, 122.7, 120.8, 90.6, 54.3. |
