Transformations of 2-(α-Furyl)- 4-(2-Oxopyrrolidinyl-1)-1,2,3,4-Tetrahydroquinolines, Cycloadducts of the Imino Diels-Alder Reaction: A Simple Synthesis of New Quinoline Derivatives

An efficient and simple synthesis of biologically important C-2 α-furyl substituted quinolines and isoindolo[2,1-a]quinolines using the same 2-(α-furyl)-4-(2-oxopyrrolidinyl-1)-1,2,3,4-tetrahydroquinolines prepared by imino Diels-Alder reaction was reported.
