The diastereoface-differentiating reaction of Grignard reagents or organolithium reagents toward chiral cyclic α-ketoenamines, prepared from the corresponding cycloalkane-1,2-dione and optically active pyrrolidine derivatives, was found to give, after hydrolysis, (R)- or (S)-α-hydroxycycloalkanones, respectively, in high enantiomeric excess.
由相应的环烷-1,2-二酮和具有光学活性的吡咯烷衍生物制备的格氏试剂或有机锂试剂与手性环α-酮烯胺的非对映异构反应发现,水解后可分别得到对映体过量的(R)-或(S)-α-羟基环烷酮。
