The recognition abilities of chiral calixarene hosts toward alkali cation guests have been exploited for the first time in asymmetric phase‐transfer catalysis. The binding affinities of a series of chiral α‐methylbenzylamine‐derived calix[4]arene‐amides toward Na+ guest have been determined by 1H NMR spectroscopic titration experiments. The good apparent association constant values are consistent...
