A study of the reaction of phenyl magnesium bromide with various N-(cyanomethyl)oxazolidines showed that product formation (essentially 3-imidazolines and 2-aminomorpholines) is highly sensitive to the substitution pattern and stereochemistry, and appears to involve initial complexation of the Grignard reagent to ring-oxygen.

The synthesis of (−)-N-Cyanomethyl-4-phenyl-1,3-oxazolidine 1 is reported. Good yields and moderate diastereomeric excesses (d.e.s.) of mono- and di-substituted α-aminonitriles were obtained from this simple chiral template.
