Pyrimidine Derivatives and Related Compounds. Part 47. A New Synthesis of Xanthines and Pyrrolopyrimidines by Intramolecular Cyclisation of 6-Substituted 5-Nitrouracil Derivatives

6-Arylalkylamino-1,3-dimethyl-5-nitrouracils (2a-f) were prepared by reaction of 6-chloro-1,3-dimethyl-5-nitrouracil (1) with arylalkylamines in the presence of triethylamine.Among them, the 6-arylalkylaminouracils (2a-d), possessing no substituent at the

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
