, p. 865 - 872 (2007/10/02)
The synthesis of various N-1 substituted ethyl 4-pyrazolecarboxylates via reaction of ethyl 2-formyl-3-oxopropionate (= ethoxycarbonylmalondialdehyde) with appropriately substituted hydrazines is described.Moreover, detailed nmr-spectroscopic investigations with the title compounds are presented.
