The reaction of thionyl chloride with dl-erythro- and dl-threo-1-phenyl-1-p-tolyl-2-benzamido-1, 3-propanediol, the compound formed by substitution of hydrogen in 1-position of 1-phenyl-2-amino-1, 3-propanediol with p-tolyl group, results in formation of oxazoline accompanied with steric inversion. Hydrolysis followed by basification afforded N-benzoylated isomers with steric configuration different from that of the starting material. This has proved that mutual conversion between threo and erythro types is possible.
