Synthesis and tautomerism study of 7-substituted pyrazolo[3,4-c]pyridines
摘要:
A number of 7-substituted pyrazolo[3,4-c]pyridine derivatives have been synthesized in order to investigate the N1-N2 tautomerism within this class of biologically interesting compounds. Tautomeric equilibrium has been studied using NMR C-13, N-15 chemical shifts and heteronuclear H-1-N-15 and H-1-C-13 spin-spin couplings, in conjunction with X-ray crystallography. The N1 tautomer predominates in DMF solution in all the compounds tested. (c) 2006 Elsevier Ltd. All rights reserved.
