10-fluoro-10-demethoxycolchicine (9) without concomitant formation of ring contraction products. Compound 9 is prepared by reaction of (diethylamino)sulfurtrifluoride with colchiceine. Unlike most reactions of colchiceine, the colchicine rather than the isocolchicine regiosiomer is the predominant product of this reaction. It was found that modification of the C-10 substituent of colchicine had a relatively
