Amplification of Chirality
Kenso Soai. 12 was > 99% and the ee was > 99.5%. Thus, 2-alkynylpyrimidyl
alkanol 12 served as a near perfect asymmetric autocatalyst [63]. During these
ten consecutive asymmetric autocatalyses, (S)-12 has automultiplied by a factor
of ca.

New Frontiers in Asymmetric Catalysis
Moreover, we found the efficient amplification of chirality by using 2-alkynyl-
5pyrimidyl alkanol 2c from as low as $ 0.00005% ee to an almost
enantiomerically pure (>99.5% ee) product in only three consecutive asymmetric
autocatalyses, [Eq.

Advances in BioChirality
Amplification of enantiomeric excess is observed in one-pot or consecutive
asymmetric autocatalyses of pyrimidyl and quinolyl alkanols. From trace amounts
of pyrimidyl and quinolyl alkanols with low e.e., increased amount of chiral
pyrimidyl ...

Organometallic Chirality
During these three consecutive asymmetric autocatalyses, the initially major (S)-
enantiomer of 2c automultiplied by a factor of ca. 630,000, whereas the initially
minor (R)- enantiomer of 2c automultiplied by less than 1,000. Scheme 4 Figure 1

Progress in Biological Chirality
The first asymmetric autocatalysis with (S)-2c of ca. 0.00005% ee gave (S)-2c in
96% yield with an enhanced ee of 57%. The second asymmetric autocatalyses
with the autocatalyst of 57% ee afforded (S)-2c with 99% ee, and the ee reached
...

It is only necessary that the conditions for its ultimate production be present—
relatively simple conditions, that bring about a series of reactions of the type
known in physiological chemistry as autocatalyses, in which one phase in the
reaction ...
It may thus be taken as a type of what goes on in cells in which such
autocatalyses are extremely common. In fact they are the most characteristic
things in cells, from a chemical point of view. If the hydantoine thus formed by the
allanturic acid ...
