Relationship between the time, yield, and enantiomeric excess of asymmetric autocatalysis of chiral 2-alkynyl-5-pyrimidyl alkanol with amplification of enantiomeric excess

Experimental and kinetic analysis of asymmetric autocatalysis with amplification of ee in the enantioselective addition of diisopropylzinc to 2-alkynylpyrimidine-5-carbaldehyde using chiral 2-alkynyl-5-pyrimidyl alkanol with low ee's are described.
