1,3-Oxazolidines are highly interesting because of their unique properties that allow them to be used in medicine and industry. They are also scientifically interesting as products of enantioselective synthesis of planar-chiral compounds [1, 2, 3]. We established previously the absolute configurations of the chiral centers of several 1,3-oxazolidines prepared from d- and l-ephedrines [4]. The various configurations of the chiral center in d- and l-ephedrines should produce various conformations of the oxazolidine ring of 2. According to several researchers [5, 6, 7, 8], the reaction of β-aminoalcohols with various aldehydes occurs usually stereoselectively or with formation of the S-stereoisomer or the R-epimer. The stereoselectivity depends usually on the nature of the reactants and solvents.

Herein we present results from a study of the reaction of d-threo-2-methylamino-1-phenyl-1-propanol (the alkaloid d-pseudoephedrine) ( 1) with previously unstudied 4-morpholinylbenzaldehyde,...
