Abstract

Chiral 1,4-dihydroquinolines were synthesized by the addition of ketene silyl acetals to quinolinium salts. The stereoselectivity was associated with the intramolecular interaction between the quinolinium and the carbonyl or thiocarbonyl groups, which was revealed by 1H NMR spectroscopy and X-ray analysis.
