Abstract
Experimental and kinetic analysis of a chemical system combines autocatalytic amplification of 2‐alkynyl‐5‐pyrimidyl alkanol 2 and 6‐alkynyl‐3‐pyridyl akanol 4 in which 2 acts as a chiral trigger and 4 being the subsequent autocatalyst. Starting from a very low initial ee, both alkanols are produced with high enantiopurity in one single cycle. This provides insight into a dual nonlinear amplification of chirality observed with amplifying trigger 2 and accelerated amplification of autocatalyst 4. These kinetic studies reveal a five‐fold magnitude superior amplification rates of 4 associated with trigger's enantiopurity at the outset.
