Dipolar Cycloaddition Reactions with Thiazolonylhydrazones: A New Route for the Synthesis of Several New Thienyl- and Furyl-Thiazolonylpyrrolopyrazole Derivatives of Expected Biological Activities
摘要:
Several new pyrrolopyrazoles were synthesized via the reactions of each of 2-thiophenecarboxaldehyde thiazolonylhydrazone or 2-furaldehyde thiazolonylhydrazone with N-substituted maleimides followed by partial dehydogenation using bromobenzene and complete aromatization using nitrobenzene. Structures were established on the basis of elemental analyses and spectroscopic data studies.
