چکیده انگلیسی
Prins-type cyclization followed by palladium-catalyzed cyclization provided sterically congested bi- or tricyclic tetrahydrofurans, which are very stereoselective as well. cis-2,5-Disubstituted tetrahydrofurans obtained from Prins-type cyclization have an allenyl group and a functional group such as alcohol, carboxylic acid, and aryl halide. The tetrahydrofurans bearing an allene group underwent palladium-catalyzed cyclization to give sterically congested bi- or tricyclic tetrahydrofurans.
Prins-type cyclization followed by palladium-catalyzed cyclization provides a very good methodology for the synthesis of various sterically congested bicyclic tetrahydrofurans, which are very stereoselective as well.
