Oxidation-active flavin models: Oxidation of α-hydroxy acids by benzo-dipteridine bearing metal-binding site in the presence of divalent metal ion and base in organic …
The oxidizing ability of benzo-dipteridine bearing a bipyridin-6-ylmethyl moiety (4) was found to be increased with Zn2+ by~ 103-fold for sulfite addition in MeOH and~ 102-fold for oxidation of an NADH model in MeCN. It was found for the first time that 4 is able to oxidize α-
