Synthesis and 1,3-Dipolar Cycloaddition Reactions of Chiral Maleimides

Molecules, 1997
New routes to the synthesis of various novel chiral maleimides are described. The oxabicyclic anhydride 2 readily available exo-Diels-Alder adduct of furan and maleic anhydride was used as a vehicle, which in turn reacted with hydrochlorides of amino ...

Polyimide (PI) films by chemical vapor deposition (CVD): Novel design, experiments and characterization [PDF]

, 2007
Polyimide (PI) has been deposited by chemical vapor deposition (CVD) under vacuum over the past 20 years. In the early nineties, studies, experiences and characterization were mostly studied as depositions from the co-evaporation of the dianhydride and ...

Mechanochemical N-alkylation of imides

Beilstein Journal of Organic Chemistry, 2017
The mechanochemical N-alkylation of imide derivatives was studied. Reactions under solvent-free conditions in a ball mill gave good yields and could be put in place of the classical solution conditions. The method is general and can be applied to various

Synthesis of Conformationally Constrained Aryl- or Heteroarylpiperazinyl Derivatives of Selected Imides as 5-HT1A Receptor Ligands

Molecules, 2006
The preparation of a number of cyclic imide 5-HT1A receptor ligandderivatives has been described. Their structures were conformationally constrained byintroducing rigid linkers containing unsaturated bonds or aromatic benzene rings.

Synthesis, anti-inflammatory, cytotoxic, and COX-1/2 inhibitory activities of cyclic imides bearing 3-benzenesulfonamide, oxime, and β-phenylalanine scaffolds: a molecular docking study

Journal of Enzyme Inhibition and Medicinal Chemistry, 2020
Cyclic imides containing 3-benzenesulfonamide, oxime, and β-phenylalanine derivatives were synthesised and evaluated to elucidate their in vivo anti-inflammatory and ulcerogenic activity and in vitro cytotoxic effects.
