The present invention pertains to the field of chemical medicine, particularly to 4-substituted coumarin derivatives and preparation methods and applications thereof. The invention provides 4-substituted coumarin derivatives with a structural formula as shown in Formula I. The invention also provides preparation methods and applications for the above 4-substituted coumarin derivatives. The compounds provided in the invention have strong anti-tumor activity with IC50 for plural tumor cell lines between 0.01-5 nM, and it also performs better to inhibit microtubule polymerization and has diversified biological activities and low toxicity, providing new options for drug-sensitive and drug-resistant tumor cells.
1-Azido-5-methyl-4-hexen-2-one was synthesized easily from 4-methyl-3-pentenenitrile which was prepared from isoprene. This compound is quite stable. Its catalytic dimerization gave 4,4-bis(3-methyl-2-butenyl)-2-butenolide.

Treatment of γ-disubstituted β,γ-unsaturatedhydroxamates with bis(collidine)bromine(I) hexafluorophosphate led mainly to the formation of cyclic bromo imidates - the thermodynamic products. Unsaturated cyclic imidates were then obtained by treatment with triethylamine. With γ-aryl β,γ-unsaturatedhydroxamates, the corresponding cyclic bromo imidates were also obtained. On treatment with triethylamine
