Abstract: The 2-(2,14-Dimethyl-pentadecanoylamin)-pentanedioic acid (I) and compounds of the formula (II), wherein the substituents have the meaning disclosed in the specification, are used as oviposition deterring pheromones against the following fruit flies (Diptera: Tephritidae) of economical importance: Anastrepha fraterculus (south America fruit fly), A. grandis, A. ludens (Mexican fruit fly), A. obliqua (mango fly), A. serpentina (sapodilla fly), A. striata (guayabi fly) and A. suspensa (Caribbean fruit fly). The above-mentioned substances, if conveniently formulated, can be used to reduce the damage caused by these insects to fruits which are cultivated in commercial and semi-commercial orchards, in garden orchards and in isolated trees in residential gardens.

Abstract: The compounds of formula I ##STR1## wherein the substituents have various significances, possess pharmacological, particularly antiinflammatory and immunosuppressant activity.They can be prepared by one or more of the following process variants: reduction, deprotection, acylation, reaction with N,N'-carbonyl- or N,N'-thiocarbonyldiimidazole, halogenation, splitting off of hydrogen halide, reaction with a hydrogen carbonate, radical deoxygenation, dehydration or reaction with diazomethane of -ethane, optionally under transient protection of reactive groups which it is not desired to react.
