Specifications | MSDS | Literature and Reviews


Bicyclo(2.2.2)oct-7-ene-2,3,5,6-tetracarboxylic acid dianhydride (COeDA, CAS number 1719-83-1) has a bicyclooctene fused with two succinic anhydrides. The rigidity of Bicyclo(2.2.2)oct-7-ene-2,3,5,6-tetracarboxylic acid dianhydride enables it to be a robust molecular scaffold for derivatization. COeDA can be derivatised by amines for succinimides while the octene favours electrophilic substitution and olefin metathesis. An inhibitor made from COeDA has shown effectiveness (half maximal inhibitory concentration IC50 = 102.2 µM) against SAR-CoV-2 main protease in the inhibition assays. The succinimide derivatives have shown blue/violet fluorescent under UV radiation, hence they can be applied in bioimaging to monitor their bioactivity.

COeDA is used to synthesize metal organic cages (MOCs) ligands. The lantern-type MOCs have record high surface area up to 521 m2/g. Those metal organic complexes can catalyse reaction of CO2 and epoxides for the purpose of carbon fixation.
