Abstract: | Synthesis of some novel pyrrolo3,4-b]pyrrole derivatives has been accomplished in good yields by the intramolecular azomethine ylide cycloaddition reaction of a strategically situated unactivated alkenyl aldehyde with various secondary amino acids. A cis fused cycloadduct was formed in all cases. |
