Article abstract of DOI:10.1021/jo00112a050

Permethylated β-cyclodextrin is a convenient chiral solvating agent (CSA) for the determination by NMR of the enantiomeric purities of chiral trisubstituted allenes and of their absolute configuration.All the allene proton resonance are deshielded, and this effect is stronger for the (S)-enantiomer of the allene than for the (R)-enantiomer.
