Functional monomers and polymers, 15. On the synthesis and reactivity of functional vinyl polymers, containing 2,4‐dioxo‐3H,10H‐benzo[h]pteridine‐10‐yl (10‐isoalloxazinyl) residues

Abstract

AbstractAs a functional vinyl monomer containing the 10‐isoalloxazinyl (2,4‐dioxo‐3H,10H‐benzo[h]pteridin‐10‐yl) residue, 10‐(2′‐methacryloyloxyethyl)‐3H,10H‐benzo[h]pteridine‐2,4‐dione (2) was prepared by reacting 10‐(2′‐hydroxyethyl)‐3 H,10H‐benzo[h]pteridine‐2,4‐dione (1) with methacryloyl chloride in hexamethyl phosphoric acid triamide solution. Polymerization and copolymerization of the monomer were carried out by 2,2′‐azoisobutyronitrile. Alternatively, vinyl‐type polymers containing the isoalloxazine system (3) were also prepared by a polymer‐analogous reaction. Dehydrogenation reaction of methylmandelate was studied with a copolymer in dimethylformamide solution.
