Staudinger-like cycloadditions between chiral, non-racemic N,N-dialkylhydrazones 1 and functionalized ketenes constitute an efficient methodology for the stereoselective construction of the β-lactam ring. The potential for fine tuning of the dialkylamino
Stereoselective cyanation of chiral α-amino aldehydes by reaction with Nagata's reagent: A route to enantiopure β-amino-α-hydroxy acids

Chiral α-dibenzylamino aldehydes react with diethylaluminum cyanide leading to anti-β-dibenzylamino-α-hydroxycyanides as the major diastereoisomers in good yields and diastereomeric excesses. Hydrolysis of the nitrile derivatives allows the synthesis of enantiopure β-amino-α-hydroxy acids.
Enantiospecific and diastereoselective synthesis of syn-β-amino-α-hydroxy acids

The reaction of chiral α-hydroxy β,γ-unsaturated esters with tosyl isocyanate followed by cyclization of the resulting allylic carbamates with iodine in the presence of sodium carbonate provided trans-4,5-disubstituted 2-oxazolidinone derivatives in a highly diastereoselective manner. The subsequent removal of the iodo group and the protective functionality afforded the syn-β-amino-α-hydroxy acids. Using the reaction sequence, (2R,3S)- and (2S,3R)-3-amino-2-hydroxy acids were synthesized with high enantioselectivity.

Novel amino acid derivatives useful as a therapeutic agent are disclosed. These amino acid derivatives and the pharmaceutically acceptable salts thereof have a human renin inhibitory effect when administered orally and are useful for treatment of hypertension, especially renin-associated hypertension.

Renin Inhibitors. Substitution of the Leucyl Residues of Leu-Leu-Val-Phe-OCH3 with 3-Amino-2-hydroxy-5-methylhexanoic Acid
Johnson, Rodney L.
, p. 605 - 610 (2007/10/02)
The 2S,3S and 2R,3S diastereoisomers of the hydroxy amino acid 3-amino-2-hydroxy-5-methylhexanoic acid (AHMHA) were synthesized and substituted for the leucyl residues of Leu-Leu-Val-Phe-OCH3 to yield the following analogues: AHMHA-Leu-Val-Phe-OCH3, AHMHA
