A highly enantioselective interrupted Povarov reaction of salicylaldimines and 2,3-dihydrofuran was developed, through the elegant Br?nsted acid catalysis of anionic chiral Co(iii) complexes. This reaction affords the cis-4-aminofuranobenzopyran derivativ

The reactions of salicylaldimines with electron-rich alkenes (2,3-dihydro-2H-furan and 3,4-dihydro-2H-pyran) catalyzed by N,N′-dioxide-Sc(OTf)3 complexes were investigated. The methodology was successfully applied to the asymmetric synthesis of

The catalytic asymmetric inverse-electron-demand (IED) [4+2] cycloaddition of various salicylaldehyde-derived N-arylimines with electron-rich alkenes in the presence of chiral BINOL-derived phosphoric acid catalysts has been studied with the aim of obtaining optically active 4-aminobenzopyran derivatives. Dienophiles such as 2,3-dihydro-2H-furan, benzyl N-vinylcarbamate and 2-vinylindole have been employed. Copyright
