An Optically Active 1-Phosphino-2-aminopropane from Ephedrine and the Stereospecific Formation of Dicarbonylcyclopentadienyl Molybdenum Complexes with these Chelate LigandThe preparation of (1R, 2S)-1-Phenyl-1-diphenylphosphino-2-N-methylamino-propane from the naturally occuring ephedrine is reported. This ligand forms with (π-C5H5)M(CO)3Cl (M = Mo, W) stereospecifically a chiral complex which rearranges - again stereospecifically - to another diastereomer.
Notes:
Die Darstellung von (1R, 2S) -1-Phenyl-1-diphenylphosphino-2-N-methylaminopropan aus dem natürlich vorkommenden Ephedrin wird beschrieben. Dieser Ligand bildet mit (π-C5H5)M(CO)3Cl (M = Mo, W) in stereospezifische Reaktion einen am Metall asymmetrischen Komplex, der sich - ebenfalls stereospezifisch - in ein Diastereomeres umwandelt.
