Absolute asymmetric amplification is observed for
pyridine alkanol by reaction with iPr2Zn vapor under heterogenous
conditions. Beside the chiral alkanol, formation of a chiral ester is observed
and identified as a subsequent Claisen-Tishchenko product of a hemiacetal
intermediate during a Soai absolute amplification.
