We thought that, when a reaction system involves asymmetric autocatalysis with amplification of ee, the initial small fluctuation of ee in racemic mixtures that arises from the reaction of achiral reactants can produce an enantiomerically enriched product. We anticipated that when i-Pr2 Zn was treated with pyrimidine-5carbaldehydes without adding any chiral substance, extremely slight enantioenrichment would be induced statistically in the initially formed zinc alkoxide of the alkanol, and that the subsequent amplification of chirality by asymmetric autocatalysis would produce the pyrimidyl alkanol with detectable enantioenrichment (Scheme 19).

Abstract This review describes the development of mechanistic understanding of amplifying asymmetric autocatalysis. After a brief description of kinetics, the main body of the work discusses the application of a variety of NMR techniques to the structure of the resting state in solution.
