(Z,Z)-Octadeca-10,12-dienoic acid was synthesised by coupling (Z)-1-bromohept-1-ene with protected undec-10-yne-1-ol. Stereoselective hydrogenation of the triple bond of the obtained enyne-system followed by deprotection yielded (Z,ZZ)-octadeca-10,12

Abstract: Bicyclic acetals play an important role as volatile signals in systems of chemical communication among many insect species, i.e. bark beetles, weevils, and moths. They represent cryptic ketodiols with a glycol- and 1,3- diol-substructure. A

The theory of SHELDONet al. (1972), stating that in marine pelagic communities biomass is distributed equally over logarithmic size classes, is tested for the inland part of the Oosterschelde. It is shown that none of the data on total particulate ma

Functional interactions between the basal ganglia and the perioral area were analyzed by means of electrical brain stimulation in the rat. The first experiment showed that unilateral stimulation of the substantia nigra sensitized the contralateral pe

The sex pheromone of the pea midge consists of 2-acetoxytridecane, (2S,11S)-diacetoxytridecane and (2S,12S)-diacetoxytridecane. The responses of male pea midges to the corresponding stereoisomers of (2S,11S)-diacetoxytridecane and (2S,12S)-diacetoxyt
