| Abstract: | Summary Condensation of ephedrine with benzaldehyde, an acid catalyzed reversible reaction, producing 3,4-dimethyl-2,5-diphenyl-1,3-oxazolidine,
was studied. If the starting reaction mixture contained acetic acid, it quantitatively reacted with ephedrine and produced
a salt functioning as an acid catalyst. On the contrary, ephedrine hydrochloride had no catalytic effect. |
