single crystal X-ray structures of 6,7-dimethoxy and diethoxy-pterins) along with 1,4-dioxanopterin is reported along with a possible mechanism for their formation by treatment of pterins with cericammoniumnitrate in methanol, ethanol, and ethylene glycol respectively. This unequivocal alkoxylation is unique only with pterin (and 5-deaza-pterin) and is unsuccessful with quinoxaline.
