Microwave-assisted [6+4]-cycloaddition of fulvenes and alpha-pyrones to azulene-indoles: facile syntheses of novel antineoplastic agents.
A microwave-enhanced [6+4]-cycloaddition reaction between 6-aminofulvene and pyrones followed by CO(2) extrusion provides azulene-indoles which display interesting antineoplastic activity.
