Syntheses of iso-condensed heteroaromatic pyrroles and the application to the total syntheses of natural products |

Abstract: | A novel method, namely the intramolecular 1,3-dipolar cycloaddition and cycloreversion of azido-alkylidene malonates, for the preparation of iso-condensed heteroaromatic pyrroles has been developed. The application of this methos for the synthesis of 2,4-dihydropyrrolo[3,4-b]indole ring system, as well as the application of this ring system for the total syntheses of ellipticine alkaloids are reported. |
