摘要

One-step microwave-assisted oxidative removal of 3-methyl and 3-sugar side chain in 2 (1H)-quinoxalinone system by selenium dioxide and sodium periodate respectively resulting 2 (1H)-quinoxalinone has been reported. Similarly xanthopterin (as acetyl derivative 11) was isolated from selenium dioxide oxidation of 7-methylxanthopterin. In the absence of adjacent lactam moiety, sodium periodate efficiently oxidizes 2-acetylaminopterin tetrols 7 and 8 to ...
