An efficient Lewis acid mediated domino Knoevenagel/hetero Diels-Alder (DKHDA) reaction of pyrazolone derivatives with N -acrylated anthranilic aldehydes was developed, which afforded functionalized tetracyclic tetrahydropyrazolo[4',3':5,6]pyrano[3,4- c ]quinolones. The products were formed in good yields and with excellent regio- and stereoselectivity in favor of the cis-configured isomer.

The synthesis of novel pyrrolidine or pyrrolizine-fused benzosultams is described. A number of (E)-N-(2-formylphenyl)-N-alkyl-2-phenylethenesulfonamides derivatives were synthesized and subjected to intramolecular [3+2] cycloaddition with azomethine ylides derived in situ from the reaction with sarcosine, phenylglycine, and L-proline.
