HERBICIDE COMPOSITIONS CONTAINING NEW MACROLID COMPOUNDS AND PROCESS FOR PRODUCING NEW MACROLID COMPOUNDS AND PHARMACEUTICAL COMPOSITIONS CONTAINING THEM AS ACTIVE COMPONENTS

摘要

Compounds of formula (I) CHEM wherein R represents a hydrogen atom or a silyl group; R1 represents a methyl, ethyl or isopropyl group; Y1 is -CH2-, Y2 is -CH- and X represents -C(R2)(R3)-[where R2 represents a hydrogen atom or a group OR6 (where OR6 is a hydroxy group or a substituted hydroxyl group having up to 25 carbon atoms) and R3 represents a hydrogen atom, or R2 and R3 together with the carbon atom to which they are attached represents @C=O, @C=CH2 or@C=NOR7 (where R7 represents a hydrogen atom or a C1-8 alkyl group and the group @C=NOR7 is in the E configuration)] or -Y1-X-Y2- represents -CH=CH-CH- or -CH2-C=C-; R4 represents a group OR6 as defined above and R5 represents a hydrogen atom or R4 and R5 together with the carbon atom to which they are attached represents @C=O. These compounds may be used for controlling insect, acarine, nematode or other pests.
