Inherent chirality was generated by regioselective monoalkylation of 1,3‐substituted calix[5]crown‐6 incorporating an axially chiral BINOL moiety, with ethyl bromoacetate. The resultant diastereomers 4a and 4b, which possess both axial chirality and inherent chirality, were readily separated by column chromatography. Respective hydrolysis afforded diastereomeric acids 5a and 5b. 1H NMR spectra and...
