Application of maleimide compound as chitin synthase inhibitor

The invention discloses an application of a maleimide compound as shown in a formula I. In the formula I, R0 is phenyl, benzyl, phenethyl, phenylpropyl, p-fluorophenyl, p-chlorophenyl, p-bromophenyl,p-methoxyphenyl, p-methylphenyl or p-hydroxyphenyl, R1 is hydrogen, methyl, phenyl or chlorine; and R2 is hydrogen, methyl, phenyl or chlorine. The provided maleimide compound has a good inhibition effect on chitin synthase.

Palladium-catalyzed aerobic oxidative carbonylation of alkynes with amines: a general access to substituted maleimides

A catalytic oxidative carbonylation reaction was developed for the synthesis of polysubstituted maleimides from alkynes and amines with air as a green oxidant. This novel transformation proceeds in the presence of palladium chloride without the need for expensive ligands or additives and has a broad substrate scope affording a variety of maleimides in good to high yields.

Hydrogenations without hydrogen: Titania photocatalyzed reductions of maleimides and aldehydes

A mild procedure for the reduction of electron-deficient alkenes and carbonyl compounds is described. UVA irradiations of substituted maleimides with dispersions of titania (Aeroxide P25) in methanol/acetonitrile (1:9) solvent under dry anoxic conditions led to hydrogenation and production of the corresponding succinimides. Aromatic and heteroaromatic aldehydes were reduced to primary alcohols in similar titania photocatalyzed reactions. A mechanism is proposed which involves two proton-coupled electron transfers to the substrates at the titania surface.
