CATIONIC POLAR CYCLOADDITION WITH ANODICALLY PREPARED α-TRI- and α-DIFLUOROMETHYLATED N,O-ACETALS: PREPARATION OF FLUOROMETHYLATED TETRA- and DIHYDROQUINOLINE DERIVATIVES

Article abstract of DOI:10.3987/COM-89-5295

Anodically prepared α-tri- and α-difluoromethylated N,O-acetals readily underwent <4⁺+2> type polar cycloadditions with styrenes and phenylacetylene in the presence of a Lewis acid to provide the corresponding fluoromethylated tetra- and dihydr
