An efficient reverse Diels–Alder approach for the synthesis of N-alkyl bismaleimides
摘要:
Bismaleimides are useful precursors for Diels-Alder reactions, Michael additions, and thiol-maleimide based conjugation for the synthesis of materials and polymers. Use of bismaleimide cross linkers for generating polymers, bioconjugate molecules, and useful imaging molecules is an active area of research. An efficient and practical synthetic protocol for N-alkyl bis-maleimide cross linkers starting from furan protected maleimide employing a reverse Diels-Alder reaction is reported.

extensively in bioconjugation reactions, but limited mechanistic studies are available regarding their hydrolysisreactions. In this paper, five single-crystal structures related with the reaction of four-step hydrolytic degradation of N,N′-ethylenedimaleimide have been investigated. On the basis of experimental results, the reaction mechanisms without or with water catalysis are proposed, which could
