FIELD: chemistry.

SUBSTANCE: invention relates to novel compounds of formula

or their salts, where R1 stands for H, C1-C6-alkylcarbonyl, C1-C6-alkoxycarbonyl, SiR7R8R9, where R7, R8, R9 independently on each other stand for C1-C6-alkyl, phenyl-C1-C2-alkoxycarbonyl, or R1 stands for trimethylsilylethoxymethyl (SEM), C1-C2-alkyl, with the latter being substituted with C6-C10-aryl, preferably phenyl, or a heterocyclic group, which represents a monocyclic saturated ring system with 5 ring atoms, one of which is nitrogen, represents hydrogen or a nitrogen-protective group. Various methods of obtaining the said compounds and their application for obtaining a NEO-inhibitor, in particular, in obtaining ethyl ether of N-(3-carboxyl-1-oxopropyl)-(4S)-(n-phenylphenylmethyl)-4-amino-(2R)-methylbutyric acid or its salts are described.

EFFECT: obtaining novel compounds.
