experimental part, p. 55 - 62 (2012/09/22)
Dichloro zinc complexes with (S)-1-phenyl-N-[(S)-1-(pyridin-2-yl)ethyl] ethanamine (PMMA) and (S)-1-(6-methylpyridin-2-yl)-N-[(S)-1-phenylethyl] ethanamine (MPMMA) were prepared and characterised by X-ray diffraction. The catalytic activity of the dimethyl complexes, generated in situ, was high in the ring opening polymerization of rac-lactide. Specifically, the dimethyl derivative of (PMMA)ZnCl2 yielded a highly stereocontrolled polylactide with Pr = 0.84.
Diastereoselective addition of methyllithium and dimethylcuprate-boron trifluoride to imines derived from (S)-1-phenylethylamine
Alvaro, Giuseppe,Savoia, Diego,Valentinetti, Maria R.
, p. 12571 - 12586 (2007/10/03)
The reactions of dimethylcuprate-boron trifluoride reagents with the imines derived from (S)-1-phenylethylamine afforded the secondary amines by addition to the Si face of the imines. (S,S)-bis(1-phenylethyl)amine and (S)-1-cyclohexylethanamine were prepa

, p. 3635 - 3642 (2007/10/02)
The synthesis of the amines 1a-f by hydrogenation of the corresponding imines 4a-f occurs with a diastereoselectivity ranging from 33percent to higher than 90percent.The absolute configurations of 1b-f have been determined by either X-ray analysis (1b and
ENANTIOSELECTIVE ADDITION OF N-BUTYLLITHIUM TO BENZALDEHYDE IN THE PRESENCE OF CHIRAL LITHIUM AMIDES
Eleveld, M. B.,Hogeveen, H.
, p. 5187 - 5190 (2007/10/02)
The reaction of n-butyllithium with benzaldehyde in the presence of chiral lithium amides 1a-e gives 1-phenyl-1-pentanol with optical yields up to 90 percent.
