Publikováno v: Synthetic Communications. 31:3685-3698

The four stereoisomers of N-2′-methylbutyl-2-methylbutylamide, the sex pheromone of the longhorn beetle Migdolus fryanus, an economically important pest of sugarcane in South America, were synthesized. The key intermediate 2-methylbutan-1-ol is com

Two diastereomers of africanol, compounds 1a and 1b, were obtained exclusively through a methodology which employed, as the key step, the nBuLi mediated intramolecular cyclization of the vinyl iodide 5. A similar cyclization of 19 provided exclusivel

Selectivity on the reaction of vinylic tellurides with butyllithium in the presence of carbonyl compounds

Autor: Vania B. Dabdoub, Francisco A. Marques, Miguel J. Dabdoub, J. T. B. Ferreira, Raquel G. Jacob

Publikováno v: Tetrahedron Letters. 40:7159-7162

The treatment of isomeric vinylic tellurides 5–7 with butyllithium in THF at −78 °C in the presence of a carbonyl compound such as benzaldehyde or cyclohexanone was studied. High selectivity of the attack at the tellurium atom was observed. In m

Pheromones and colonization: reassessment of the milkweed bug migration model (Heteroptera: Lygaeidae: Lygaeinae)

Autor: J. T. B. Ferreira, D. Liewehr, J. E. Oliver, T. Taghizadeh, Jeffrey R. Aldrich

Publikováno v: Chemoecology. 9:63-71

Research on insect migration has justifiably emphasized females – the so-called “oogenesis-flight syndrome”– since it is the females that place the eggs into new habitats. The large and small milkweed bugs, Oncopeltus fasciatus and Lygaeus ka

Field responses of stink bugs to the natural and synthetic pheromone of the Neotropical brown stink bug, Euschistus heros (Heteroptera: Pentatomidae)

Autor: Kenji Mori, J. T. B. Ferreira, Paulo H. G. Zarbin, F. G. V. Schmidt, Miguel Borges, Edison R. Sujii, Maria Alice de Medeiros

Publikováno v: Physiological Entomology. 23:202-207

The synthetic racemic mixture of methyl 2,6,10-trimethyltridecanoate, a component of the male produced pheromone of Euschistus heros (F.) (Heteroptera, Pentatomidae), was attractive to pentatomid species in a field test, using homemade pheromone trap
