Cycloaddition of electron-rich chalcone epoxides with N-arylimines was efficiently catalyzed by tris(4-bromophenyl)aminium hexachloroantimonate producing poly-substituted 1,3-oxazolidine derivatives in good yield.
Cycloaddition of electron-rich chalcone epoxides with electron-rich olefins was efficiently catalyzed by tris(4-bromophenyl)aminium hexachloroantimonate producing poly-substituted tetrahydrofuran derivatives in high yield.
