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

摘要

The presente invention relates to pesticidal compounds of general formula (I):
wherein ----- represents a carbon-carbon single or double bond; ---- Aۥ represents -CH(R 4 )-, if said carbon-carbon bond is a single bond, wherein R 4 represents, independently, hydrogen, alkoxy or substituted alkoxy, or R 1 and R 4 , taken togehter, form an alkylidenedioxy or substituted alkylidenedioxy group; or --- Aۥ represents =C(R 5 )-C(=O)-, if said carbon-carbon bond is a double bond, wherein R 5 represents hydrogen or halogen; R 1 and R 2 represent, independently, hydrogen, halogen, alkoxy, substituted alkoxy or an ester group, or R 1 and R 2 , taken together with the carbon atoms to which they are attached, represent an oxirane ring; or R 1 and R 2 , taken together, represent an alkylidenedioxy or substituted alkylidenedioxy group; R 3 represents -CH 2 R 6 (wherein R 6 represents an ester group), oxiranyl, or a group of formula
wherein R 7 represents hydrogen or alkyl; R 8 represents phcnylsulfanyl, phenylselenyl, phenylsulfoxy or phenylselenoxy; and R 9 represents hydrogen, ethoxycarbonyl or carbamoyl; as well as to the process for the preparation of these compounds, their utilisation as pesticides and to the method of application of the same to said pests or their locus.
