The most important stereodynamic feature of carbonhelicenes is the interconversion of their enantiomers. The Gibbs activation energy (ΔG≠ (T)) of this process, which determines the rate of enantiomerization, dictates the configurational stability of nhelicenes. High values of ΔG≠ (T) are required for applications of functional chiral molecules incorporating nhelicenes or helicene substructures. This minireview provides an overview of the mechanism, recent developments, and factors affecting the enantiomerization of nhelicenes, which will accelerate the design process of configurationally stable functional chiral molecules based on helicene substructures. Additionally, this minireview addresses the misconception and irregularities in the recent literature on how the terms "racemization" and "enantiomerization" are used as well as how the activation parameters are calculated for nhelicenes and related compounds.
