Compounds with acaricidal, insecticidal and anthelmintic activities have the formula: ##STR1## wherein: --X--Y-- is selected from the group consisting of --CH 2 --CH 2 --, --CH 2 --CHOH--, --CH═CH--, and --CH 2 --C(═O)--; n R 1 is selected from the group consisting of a methyl group, an ethyl group, an isopropyl group, a sec-butyl group and groups of formula --C(CH 3 )═CHR 5 in which R 5 is selected from the group consisting of a methyl group, an ethyl group and an isopropyl group; n R 2 represents a group of formula --(CH 2 ) n --C(R 6 )═C(R 7 )(R 8 ) in which n is 0, 1 or 2, R 6 and R 7 each is selected from the group consisting of a hydrogen atom and a methyl group and R 8 is selected from the group consisting of a hydrogen atom, a C 1-4 alkyl group, a phenyl group and a phenyl group substituted with at least one substituent selected from the group consisting of halogen, methyl and nitro substitutents; n R 3 is selected from the group consisting of a hydrogen atom, a methyl group, a hydroxy-protecting group, an ester-forming carboxylic acid residue, and an ester-forming carbonic acid residue; and n R 4 is selected from the group consisting of a hydrogen atom and an α-L-oleandrosyl-α-L-oleandrosyloxy group, with the proviso that R 4 represents a hydrogen atom when the group R 1 is selected from the group consisting of a methyl group, an ethyl group, and groups of formula --C(CH 3 )═CHR 5 in which R 5 is selected from the group consisting of a methyl group, an ethyl group and an isopropyl group. |
