Abstract

Fungicidally active novel E-isomers of N.sup..alpha. -(2-cyano-2-alkoximino-acetyl)-amino acid derivatives and peptides of the general formula (I) ##STR1## in which R represents alkyl, alkenyl, alkinyl, cyanoalkyl, azolylalkyl or optionally substituted phenylalkyl, or represents optionally substituted cycloalkyl; PA0 R.sup.1 represents hydrogen, alkyl, optionally substituted phenyl or optionally substituted benzyl, or represents alkoxycarbonylamino; PA0 R.sup.2 represents hydrogen or alkyl; PA0 R.sup.3 represents hydrogen, alkyl, alkoxycarbonylalkyl, hydroxycarbonylalkyl, aminocarbonylalkyl, azolylalkyl, cyanoalkyl, hydroxyalkyl, alkenyl, alkinyl or optionally substituted cycloalkyl, or represents optionally substituted phenyl or phenylalkyl, or represents the grouping EQU R.sup.4 --SO.sub.n --Z-- PA0 R.sup.4 n and Z having various meanings, and PA0 X is --OH--OR.sup.1 or --NR.sup.2 R.sup.3.
