5,7-disubstituted 7H-pyrrolo[2,3-d]pyrimidin-4(3H)-ones 2 were synthesized by the cyclocondensation of 1,4-disubstituted 2-amino-3-cyanopyrrole 1 with formic acid. When comparative study of N versus O alkylation of ambident 5,7-disubstituted 7H-pyrrolo[2,3-d]pyrimidin-4(3H)-ones 2 was carried out under liquid-liquid PTC, solid-liquid PTC, and solid-liquid solvent free conditions using various alkylating agents 3, the N-alkylated product 4 were obtained selectively and exclusively.

There are currently no clinically useful inhibitors against metallo-β-lactamases (MBLs), enzymes that confer resistance against a broad spectrum of commonly used antibiotics and that are produced by an increasing number of bacterial pathogens. New pyrrole
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.
