Abstract

Absolute asymmetric amplification is observed for pyridine alkanol by reaction with iPr 2 Zn 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.
