6-SUBSTITUTED INDANOYL AMINO ACID CONJUGATES AS MIMICS TO THE BIOLOGICAL ACTIVITY OF CORONATINE

摘要

Described are 6-substituted indanoyl amino acid conjugates of the chemical Formula (I) wherein R1= (II), R2 R5 have the meanings given in the description, and X = a halogen atom; as potent plant elicitors and efficient mimics of the phytotoxin coronatine. Also, processes for producing the improved elicitors are provided, which allow a rapid and convenient access to large quantities of the highly active compounds. Furthermore, there are compositions and plant protecting agents described, comprising as active ingredient a compound of the present invention. The plant protecting agents are useful for inducing resistance to pathogens in plants. The compositions may also be used to selectively induce senescence in fruit of plants.
