Insight into the catalytic activity of alloxazinium and isoalloxazinium salts in the oxidations of sulfides and amines with hydrogen peroxide
Original language description
In addition to the already known organocatalysts dihydro-5-ethylalloxazines 1-H2 and 5-ethylisoalloxazinium salts 2, other derivatives of alloxazines and isoalloxazines (flavins) have been shown to catalyze the oxidation of sulfides to sulfoxides with hydrogen peroxide with high efficiency. In the alloxazine series, the C4a-methoxy adduct 1-OCH3 or 5-ethylalloxazinium salts 1 can also be used, but the latter only in the presence of a base, as a co-catalyst. In the isoalloxazine series, the C4a-hydroxy adduct 2-OH or dihydroform 2-H2 can also be utilized but only in the presence of the catalytic amount of an acid. On the other hand, only alloxazine derivatives, i.e. dihydroalloxazines 1-H2 and their methoxy adducts 1-OCH3 or alloxazinium salts 1 can beused as catalysts for the oxidation of tertiary amines, as the catalytic activity of isoalloxazinium salts 1 and their derivatives is inhibited under basic conditions. The different reactivity of the alloxazinium and isoalloxazinium catal
