Asymmetric conjugate addition to prochiral to prochiral cyclic enones was devised by using copper azaenolates derived from an acetone imine of optically active amino ethers which were prepared from α-amino acids, the optical yields of the resulting 3-acetonylcycloalkanones being found to attain as high as 75% e. e.
通过使用由α-氨基酸制得的旋光氨基醚的丙酮亚胺的丙酮亚胺衍生的铜氮烯酸酯,设计了从手性至前手性环状烯酮的不对称共轭加成物,发现所得到的3-丙酮基环链烷酮的光学收率高至75%ee
