Synthesis of fused tetrazolo[1,5- c]pyrrolo[3,2-e]pyrimidines and their reductive conversion to new 4-aminopyrrolo[2,3-d]pyrimidines

Some new 7,9-substituted 7 H -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-disubstitute

Improved synthesis and efficient chemoselective reduction of fused tetrazoles under phase-transfer conditions

Liquid-liquid phase-transfer conditions were employed in an improved synthesis of 7,9-substituted 7H-pyrrolo[3,2-e]tetrazolo[1,5-c]pyrimidines and 5,7-substituted 4-amino-7H-pyrrolo[2,3-d]pyrimidines. The latter were obtained either by reductive ring clea
