, p. 2121 - 2127 (2001)
The Friedel-Crafts reactions of chiral N-(2,2,2-trifluoroethylidene)-1-arylethylamines 1a and 1b with various electron-rich aromatic compounds were examined. The reactions proceeded readily at room temperature in the presence of BF3·Et2O. Substituted products 2-12 were obtained in low to very high stereoselectivities (up to 100% d.e.). The absolute configuration of compound 12 was determined by X-ray analysis. Moreover, the chiral auxiliary from compounds 3 and 12 was selectively removed by palladium-catalyzed hydrogenolysis.
