The heptakis(2,3,6-tri-O-methyl)-β-cyclodextrin (TRIMEB) has been successfully used as convenient chiral solvating agent to determine the enantiomeric composition of chiral trisubstituted allenes by 1H NMR spectroscopy: the analysis of the effect of the molar ration TRIMEB/allene, temperature, and nature of the solvent allowed us to optimize the experimental conditions to enhance the separation between the signals of the two enantiomers of each allene.
