2,6-Dioxo-(1H,3H)-9-N-ribitylpurine (6) and 2,6-dioxo-(1H,3H)-8-aza-9-N-ribitylpurine (7) have been synthesized and evaluated as inhibitors of lumazine synthase and riboflavin synthase. Reaction of 5-amino-6-ribitylaminouracil hydrochloride (8) with diethoxymethyl acetate (9) afforded the purine 6, while diazotization of 8 afforded the 8-aza purine 7.

The synthesis of D-mannosyl, D-galactosyl and D-glucosyl theophylline nucleosides by diethoxymethyl acetate (DEMA)-induced cyclization of 4-amino-5-glycosylideneimino-1,3-dimethyluracil is reported. 8-Methyltheophylline derivatives of the same sugars were also prepared by Ac(2)O/H(+)-induced cyclization of their imine precursors. This approach has allowed beta-D-mannopyranosyl-, alpha-D-galactofuranosyl-
