摘要：
Sciff bases 1 and 2, which were derived from chiral aminoalcohols, were used as ligands in Ti-catalyzed asymmetric alkynylation of aldehydes. Good enantioselectivities (up to 88% ee) and high chemical yields (80-90%) were obtained. (c) 2007 Ying Shu Li. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.
