Reactions of Chiral Imines with Dienes

Moderate selectivities were observed in non-catalyzed and Lewis acid-promoted aza Diels-Alder reactions of non-activated imines with cyclopentadiene and 1,3-butadienes. [Pg.77]

Reactions of C-Acylimines with a Chiral Nitrogen-Substituent [Pg.78]

Reactions of C-acylimines derived from phenylethylamine and glyoxylate proceed highly stereoselective in the presence of trifluoroacetic acid. [Pg.78]

Stereoselective aza Diels-AIder reactions of A-acyliminimn species derived from chiral glyoxylates have been intensively studied. The highest selectivities are obtained with 8-phenyhnenthyl glyoxylate derivatives. [Pg.79]

Highly stereoselective aza Diels-Alder cycloadditions have been observed in reactions of chiral A-acylimines bearing two chiral moieties with cyclopentadiene (matched pair) and 1,3-butadienes in the presence of trifluoroacetic acid. [Pg.80]
