Solvent-free regioselective synthesis of 6- and 7-substituted pteridines under microwave irradiation

Reactions of 5,6-diaminouracils with α-keto aldehydes over acidic and neutral aluminum oxide under microwave irradiation gave the corresponding 6- and 7-substituted 1,2,3,4-tetrahydropteridine-2,4-diones in 63-79% yield with high regioselectivity. Pleiade

The Oxidation of 6- and 7-Aryl-4(3H)-pteridinones by Immobilized Arthrobacter M-4 Cells Containing Xanthine Oxidase

The preparation of 6- and 7-(pX-phenyl)-4(3H)-pteridinones (X = H, CH3, OCH3) is described.The oxidation of these compounds by (immobilized) Arthrobacter M-4 cells containing xanthine oxidase has been studied.The oxidation monitored by uv spectroscopy usually goes fast, except for 7-(pX-phenyl)-4(3H)-pteridinones (X = CH3, OCH3), which are slowly oxidized.With bacterial cells immobilized in gelatine crosslinked with glutaraldehyde small laboratory-scale oxidations were carried out.Based on spectral data the products of the oxidation reactions are 6- and 7-aryllumazines.
