Lanthanide-induced shift studies were performed using a chiral lanthanide shift reagent Eu(hfc)3.Simple ethers exhibited little complexation to the shift reagent.Simple aldehydes produced large lanthanide-induced shifts.The α-alkoxy aldehydes gave lanthanide-induced shifts consistent with contributions from a "chelated" species.The degree of chelation was dependent on the steric bulk of the alkyl side chain.
