Sugar derivatives comprising oxiranes or alpha, beta-unsaturated gamma-lactones, process for their preparation and their utilisation as pesticides

摘要

The present invention relates to pesticidal compounds with general formula (I), their preparation and application to said pests or their locus, wherein represents C—C single or double bond; represents —CH(R₄)—, if said C—C is a single bond, R₄ hydrogen, alkoxy or substituted alkoxy, or R₁, R₄, taken together, form an alkylidenedioxy or substituted alkylidenedioxy group; or represents ═C(R₅)—C(═O)—, if said C—C is a double bond, R₅ hydrogen, halogen; R₁, R₂-hydrogen, halogen, alkoxy, substituted alkoxy or ester group, or R₁, R₂, taken together with the carbon atoms to which they are attached, represent an oxirane ring; or R₁, R₂, taken together, represent an alkylidenedioxy or substituted alkylidenedioxy group; R₃ represents —CH₂R₆ (R₆-ester group), oxiranyl, or a group of formula wherein R₇ is hydrogen or alkyl, R₈ phenylsulfanyl, phenylselenyl, phenylsulfoxy or phenylselenoxy; and R₉ hydrogen, ethoxycarbonyl or carbamoyl.
