摘要：

ee Values in excess of 80% can be achieved in CC coupling reactions of 1‐naphthol with pyruvate esters using the chiral Lewis acid 1 as catalyst. Complex 1 is available from (+)‐camphor via a five‐step synthesis with an overall yield of ca. 30%. (Figure Presented.) Copyright © 1990 by VCH Verlagsgesellschaft mbH, Germany
