β-Amino esters derived from the stereoselective conjugate addition of homochiral lithium N-benzyl-N-α-methyl-4-methoxybenzylamide to α,β-unsaturated esters may be orthogonally mono-N-deprotected under either oxidative or acid-promoted reaction conditions. Further oxidative deprotection affordsβ-amino acids or β-lactams.

A new chiral tetrameric zinc complex [(1)ZnEt]4 (2) has been readily prepared via alkane elimination between ZnEt2 and a chiral azetidine derivative, (2R,3R)-1-[(1S)-1-(4-methoxyphenyl)ethyl]-2-phenyl-3- hydroxyazetidine (1H). Complex 2 has been characterized by various spectroscopic techniques, elemental analyses, and X-ray diffraction analysis. Complex 2 has a cubane-like Zn4O4 core structure, and is an active catalyst for the polymerization of rac-lactide, leading to the heterotactic-rich polylactides.
The asymmetric synthesis of β-haloaryl-β-amino acid derivatives

, p. 1257 - 1260 (2007/10/03)
Lithium N-benzyl-N-α-methyl-4-methoxybenzylamide is employed as a homochiral ammonia equivalent for the asymmetric synthesis of β-haloaryl-β-amino acid derivatives using a conjugate addition/oxidative deprotection strategy.
