PROCESS FOR THE PREPARATION OF ISOMERS AND DERIVATIVES AND PEPTIDES OF N-ALPHA (2-CYAN-2-ALCOXYMINE-ACETYL) -AMINO ACIDS, PESTICIDED COMPOSITES, PROCESSES FOR COMBATING PARASITES AND FUNGI AND FOR THE PREPARATION OF COMPOSITES

摘要

Fungicidally active novel E-isomers of N alpha -(2-cyano-2-alkoximino-acetyl)-amino acid derivatives and peptides of the general formula (I) IMAGE (I) in which R represents alkyl, alkenyl, alkinyl, cyanoalkyl, azolylalkyl or optionally substituted phenylalkyl, or represents optionally substituted cycloalkyl; R1 represents hydrogen, alkyl, optionally substituted phenyl or optionally substituted benzyl, or represents alkoxycarbonylamino; R2 represents hydrogen or alkyl; R3 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 R4-SOn-Z- R4 n and Z having various meanings, and X is -OH-OR1 or -NR2R3.
