Extremely high enantioselectivity (> 99.5% ee) and chemical yield (> 99%) are achieved in an asymmetric autocatalytic reaction. A (5- pyrimidyl)alkanol with a tert-butylethynyl group at its 2-position (1) is a very efficient asymmetric autocatalyst in the enantioselective alkylation in Equation (1).

A new series of aza-substituted analogues 3-5 based on the 1,4-bis(phenylethynyl)benzene moiety have been synthesized by the selective Pd-catalyzed Sonogashira coupling reaction from 5-bromo-2-iodopyrimidine (1). In these linear molecules, the dipolar pyr
