Microwave-assisted [6+4]-cycloaddition of fulvenes and α-pyrones to azulene–indoles: Facile syntheses of novel antineoplastic agents
摘要:
A microwave-enhanced [6 + 4]-cycloaddition reaction between 6-aminofulvene and pyrones followed by CO2 extrusion provides azulene-indoles which display interesting antineoplastic activity. (C) 2001 Elsevier Science Ltd. All rights reserved.

In contrast to the Diels–Alder reaction of fulvenes and pyrones, fulveneketene acetal reacts with α-pyrone to give the [6 + 4] cycloaddition adduct, an efficient and novel route to the azulenols.
