Various oxazolidines were prepared from ephedrine.It was shown that their formation is not general, the reaction is not always stereoselective and can lead to isomerization of the double bond of α,β-unsaturated aldehydes.Some of these oxazolidines were used in stereoselective preparation of β-alkyl aldehydes.

Methyl copper reacts with the 2(-)R oxazolidine (93percent optically pure) obtained from cinnamaldehyde and 1-ephedrine and leads to S(+)3-phenyl butanal with an enentiomeric excess of 35percent.
