Synthesis of deaminocolchinyl methyl ether 9 was achieved from tetramethoxy-substituted biphenyl-2-carb-aldehyde 12via tricyclic ketone 20 and 5,6-didehydro congener 11. Compound 9 was identical in every respect with material prepared from colchicine via 6,7-didehydro congener 10. Measuring inhibition of tubulin polymerization in vitro showed compounds 4, 5, and 9–11 of the alloseries of colchicinoids
由四甲氧基取代的联苯-2-碳-醛12经由三环酮20和5,6-二氢同系物11合成了脱氨基联苯甲酰基甲基醚9。化合物9在各个方面与经由秋水仙碱经6,7-二氢同系物10制备的材料相同。测量微管蛋白聚合的抑制在体外表现出的化合物4,5,和9 - 11秋水仙碱的alloseries的是特别有效的抑制剂。
