Asymmetric synthesis of dihydroquinolines by addition of organometallic rea
gents on a chiral 3-quinolinyl aminal was studied. 1,2-Adducts were obtaine
d with good regio- and diastereoselectivity. The absolute configuration for
1,2-adducts was determined by X-ray analysis and for 1,4-adducts by chemic
al correlation. (C) 1999 Published by Elsevier Science Ltd. All rights rese
