Abstract Colchicine was formally synthesized from 4-hydroxytropolone in a few-step sequence. The key step of the synthesis is palladium (0)-catalyzed ethynylation of 4-(trifluoromesyloxy)-2-methoxytropone. The... present method has a potential in synthesizing various structurally modified colchicine derivatives.show more
