Syntheses of 1,3-disubstituted-5a-hydropyrrolo[2,3-d]quinazolino[3,2-e] pyrimidin-6(5H)-ones: A comparison of conventional and microwave technique

An exclusive new ring system of 1,3-disubstituted-5a-hydropyrrolo[2,3-d] quinazolino [3,2-e]pyrimidin-6(5H)-ones 4 has been synthesised from 4-chloropyrrolo[2,3-d]pyrimidines 2 which are prepared using phase transfer catalysts. The synthesis 4 highlights

Synthesis of 7H-tetrazolo[1,5-c]pyrrolo[3,2-e]pyrimidines and their reductive ring cleavage to 4-aminopyrrolo[2,3-d]pyrimidines

Some new 7,9-disubstituted 7H-1,2,3,4-tetrazolo[1,5-c]pyrrolo[3,2- e]pyrimidines 5 have been synthesized either by diazotization of 4-hydrazino- 5,7-disubstituted-7H-pyrrolo[2,3-d]pyrimidines 4 obtained by hydrazinolysis of 4-chloro-5,7-disubstituted-7H-pyrrolo[2,3-d]pyrimidines 3 or via a substitution reaction between 3 and sodium azide. 5,7-Disubstituted-7H- pyrrolo[2,3-d]pyrimidin-4(3H)-ones 2 were obtained by cyclocondensation of 2- amino-3-cyano-1,4-disubstituted pyrroles 1 with formic acid which on chlorination using phosphorus oxychloride afforded 3. A novel route for the synthesis of 4-amino-5,7-disubstituted-7H-pyrrolo[2,3-d]pyrimidines 6 by the reductive ring cleavage of 5 has been reported.
