Embodiment 1
[0023] Preparation of N-5-fluorouracil acetic acid 4′-nor-4-deoxypodophyllotoxin ester
[0024] Take 77 mg (0.2 mmol) of the compound of formula III and dissolve it in 10 ml of dry dichloromethane, add N-5-fluorouracil acetic acid (40 mg, 0.22 mmol) and a catalytic amount of N, N-dimethylaminopyridine at room temperature under nitrogen protection, Stirring was continued until the reaction was completed. The white solid compound was separated by direct column chromatography. The detection data of the product obtained by the reaction are as follows:
[0025] Yield: 62%; m.p.: 180-182°C; (c 0.3, CHCl 3 ); IR (cm -1 ) 3194, 3072, 3004, 2943, 2915, 2844, 1773, 1706, 1670, 1601, 1505, 1483, 1463, 1420, 1378, 1337, 1227, 1159, 1130, 1093, 1037, 996; 1 HNMR (400MHz, CDCl 3 )δ9.40(br, 1H, NH), 7.31(d, J=5.6Hz, 1H), 6.67(s, 1H), 6.51(s, 1H), 6.39(s, 2H), 5.95(d, J =7.6Hz, 2H), 4.77(s, 2H), 4.63(d, J=4.4Hz, 1H), 4.46(t, J=8.8Hz, 1H), 3.92(t, J=8.8Hz, 1H), 3.70(s, 6H, 2OMe), 3.07...
