Maleimide derivative as well as preparation method and application thereof

The invention discloses a maleimide derivative as well as a preparation method and application thereof. The structural general formula of the maleimide derivative is shown as a formula I, wherein R1 and R2 are respectively and independently selected from

A mild and selective protecting and reversed modification of thiols

One selective thiol-protecting study has been investigated for a wide range of thiols including general thiols and thiols containing multiple functional groups. The reactions of bromomaleimides and thiols under the mild condition afforded the protected products in excellent yields. The thiols can be recovered very quickly using dithiothreitol (DTT) under the mild condition.

A mild synthesis of N-functionalised bromomaleimides, thiomaleimides and bromopyridazinediones

Bromomaleimides are useful building blocks in synthesis and powerful reagents for the selective chemical modification of proteins. A mild new synthesis of these reagents is described, along with the convenient transferability of the approach to dithiomale
