Sažetak

D-Nor - pseudo- ephedrine was prepare d from N-phthaloyl-D-alanyl chloride through the intermediate D-a-phthalimido-propiophenone which was reduced with aluminum isopropoxide to the appropriate carbinol. L-Nor- pseudo-ephedrine was prepared in the same way from L-alanine. The configurational correlation between D-nor-pseudo-ephedrine and D-alanine a nd L-nor- pseudo-ephedrine and L-alanine was established. The configurational relation of C(2) atom of chloramphenicol and D-(-)-nor - pseudo - ephedrine was thus established since chloramphenicol was previously synthetized from D-serine.
