    摘要: The invention relates to a process for the preparation of peptides of the general formulaArg--Lys--S--Val--Yin which S denotes glutamic acid or .alpha.-aminoadipic acid and Y denotes tyrosine or tryptophan or esters or amides thereof, which comprises subjecting tetrapeptides of the formulaZ--Arg(Z'.sub.2)--Lys(Z')--S--(Bzl)--Val--OHin which Z' represents a protective group of the benzyl type, to a condensation reaction with corresponding tyrosine esters or amides or tryptophan esters or amides and removing the protective groups by hydrogenation. The invention furthermore relates to tetrapeptides as intermediate products of this process.
