| Research Abstract |
Asymmetric autocatalytic reaction of 2-methyl-1- (5-pyrimidyl) -1-propanol (1) was examined. (S) -1 with high e.e.worked as an asymmetric autocatalysis in the reaction of pyrimidine-5-carbaldehyde and diisopropylzinc to afford (S) -1 with high e.e. When (S) -1 with low e.e.was employed as an asymmetric autocatalyst, the newly formed (S) -1 had an higher e.e. By using the newly formed (S) -1 as the asymmetric autocatalyst for the next reaction, the e.e. of (S) -1 reached 90%e.e. Quinolyl alkanol is also an asymmetric autocatalysis to afford itself with 94% e.e.in the reaction of quinoline-3-carbaldehyde and diisopropylzinc.
