  Synthesis of novel mannich bases containing Pyrazolones and indole systems

  摘要：

  Novel mannich bases 7 a-h were synthesized the condensation reaction between 3-Methyl-5-oxo-4-(4'-phenyl hydrazono)-4,5-dihydro-pyrazol-1-yl]acetic acid hydrazide 4 With Isatin yielded the corresponding [3-Methyl-5-oxo-4-(4'-substituted aryl hydrazono)-4,5-dihydro-pyrazol-1-yl]-acetic acid(2-oxo-1,2-dihydro-indol-3-ylidene)-hydrazide 6, this was subjected to mannich reaction with cyclic secondary amines in the presence of formaldehyde in DMF to give corresponding hydrazide 7 in excellent yields. The structures of these newly synthesized compounds were characterized by (1)H-NMR, Mass, IR and elemental analysis.
