Hydrazones obtained from α-diazo esters were converted to pyrroles when heated with thionyl chloride in alcohol. Among hydrazones, those substituted with a benzene ring on the β-carbon to the ester are likely to give pyrroles in good yields.

We have developed a novel method for the synthesis of 3,4-diarylpyrrole-2,5-dicarboxylates via α-diazo esters, which are easily obtained from phenylalanine derivatives. Utilizing this method, intermediates of bioactive compounds having the structure of 3,

Versatile electrophiles N-acylhydrazones are synthesized via diazotization, reduction, and acylation of α-amino acid esters. Reduction of diazo esters with L-selectride or tributylphosphine affords the corresponding hydrazones in good yields. Both reducin
