NEW SYNTHESIS OF 1,3-DIMETHYL-7-HYDROXYPYRROLOPYRIMIDINE-2,4(1H,3H)-DIONES (9-HYDROXY-9-DEAZATHEOPHYLLINES)

Treatment of 5-nitro-1,3,6-trinitrouracil with aryl aldehydes in the presence of piperidine causes the condensation to the 5-nitro-6-styryl-uracil derivatives, followed by the intramolecular cyclization including piperidine-catalyzed oxidation-reduction t

Syntheses of 9-Deazatheophyllines and 6-Deoxy-9-deazatheophyllines

The reaction of 1,3-dimethyl-5-nitro-6-styryluracils (IIa-e) with sodium dithionite in formic acid afforded the corresponding 8-aryl-9-deazatheophyllines (IVa-e).The reaction of IVa with phosphorus oxychloride gave 6-chloro-6-deoxy-8-phenyl-9-deazatheophy
