Asymmetric autocatalysis of a ferrocene-containing chiral compound with amplification of chirality

Chiral ferrocene-containing pyrimidyl alkanol can be efficiently synthesized via asymmetric autocatalysis as an enantiomerically pure product. Moreover, a remarkable positive nonlinear effect occurs during this autocatalytic reaction. Starting from a nearly racemic seed, it is thus possible to produce a larger amount of the same compound with high ee.
