摘要：

4-Hydroxy-1,2-dihydro-2-quinolinones undergo facile intramolecular domino Knoevenagel hetero Diels-Alder reactions with o-prenylated aromatic aldehydes and the aliphatic aldehyde citronellal, to afford novel pyranoquinolinone derivatives. A high degree of chemoselectivity has been achieved under microwave irradiation condition. (C) 2002 Elsevier Science Ltd. All rights reserved.
