LiBF₄-Catalyzed Imino-Diels-Alder Reaction: A Facile Synthesis of Pyrano- and Furoquinolines [1]

Abstract

Lithium tetrafluoroborate efficiently catalyzes the imino-Diels-Alder reaction of aldimines with 3,4-dihydro-2H-pyran (DHP) and 2,3-dihydrofuran to afford the corresponding pyrano- and furoquinolines in high yields with high diastereoselectivity.

Key words

lithium tetrafluoroborate - imino-Diels-Alder reaction - tetrahydroquinolines
