摘　　要：Efficient nitrosonium （NO＋）-initiated aza-Diels-Alder reactions of N-arylimines with 2,3-dihydrofuran or 3,4-dihydro-2H-pyran allowed access to furano[3,2-c]- or pyrano[3,2-c]quinolines. A mixture of cis and trans-quinoline isomers was obtained in various ratios and yields.Efficient nitrosonium （NO＋）-initiated aza-Diels-Alder reactions of N-arylimines with 2,3-dihydrofuran or 3,4-dihydro-2H-pyran allowed access to furano[3,2-c]- or pyrano[3,2-c]quinolines.
