Synthesis of the hydroxyethylene dipeptide isostere, (2S,4S,5S)-5-amino-6-cyclohexyl-4-hydroxy-2-isopropyl hexanoic acid n-butyl amide

A stereoselective synthesis of the hydroxyethylene dipeptide isostere, (2S,4S,5S)-5-amino-6-cyclohexyl-4-hydroxy-2-isopropyl hexanoic acid-n-butyl amide from Boc-L-phenylalanine is described.

Diastereoselective Synthesis of the Hydroxyethylene Dipeptide Isostere of Leu-Val

The synthesis of hydroxyethylene dipeptide isostere of Leu-Val, a transition-state mimic, is described.The key steps of this synthetic approach are the homogeneous asymmetric hydrogenation of γ-keto esters by BINAP-Ru(II) complex, and the construction of
