STUDIES ON DIMETHYLHYDRAZONES OF HETEROARYL ALDEHYDES. THE REACTIVITY OF 2-FORMYLFURAN, 2-FORMYLTHIOPHENE AND 1-METHYL-2-FORMYLPYRROLE N,N-DIMETHYLHYDRAZONES WITH METHYL PROPIOLATE AND DIETHYL AZODICARBOXYLATE

The title hydrazones react with methyl propiolate giving the new 2-heteroarylpyridines (4, 5 and 6).The reaction with diethyl azodicarboxylate gives 1:1 Michael adducts except with formylthiophene hydrazone that gives the compound (14) a novel type of 1:1 adduct.
