After stirred for 12 h, the rection ws quenched y slow ddition of queous st. NHCO 3 solution (60 ml) nd wter (40 ml) t 0 o C. The orgnic lyers were extrcted with AcOEt (40 ml 3) nd wshed with rine (40 ml). The comined orgnic lyers were dried over N 2 SO 4 nd concentrted. The crude product ws purified y column chromtogrphy (hexne:acoet = 3:1) to otin the title compound: red solid; 75% (32.7 mg) (Supplementry Figure S29); 1 H NMR (400 MHz, CDCl 3 ) δ 7.12 (dt, J = 9.2, 2.6 Hz, 2H), 6.86 (d, J = 2.0 Hz, 1H), 6.75 (dt, J = 8.8, 2.6 Hz, 2H), 6.49 (d, J = 2.4 Hz, 2H), 6.43 (t, J = 2.2 Hz, 2H), 3.86 (s, 3H), 3.76 (s, 3H), 3.70 (s, 6H), 3.61 (s, 3H).; 13 C NMR (100 MHz, CDCl 3 ) δ 196.6, 162.5, 160.2, 158.7, 156.6, 154.7, 137.0, 134.1, 131.0, 130.6, 123.6, 122.7, 113.4, 106.5, 104.1, 102.7, 101.0, 55.9, 55.7, 55.3, 55.1; HRMS (ESI) clcd. for C 26 H 24 NO + 6 [M+N] + : ; found: ; The spectrl dt were identicl to those reported in the literture. 49 Supplementry References 59.
