Abstract

The 1, 3-dipolar cycloaddition reactions of various N-tethered alkenyl aldehydes with some cyclic and acyclic amino acids have been studied. Some key sulfonamides having strategically positioned aldehyde and olefinic tether have been synthesized and effectively subjected to intramolecular azomethine ylide cycloaddition reaction resulting in a series of pyrrolo [3, 4-b] pyrrole and its N-1–C-2 derivatives, and a series of novel heterotricyclic ...
