The Comstock mealybug (CMB) Pseudococcus comstocki (Kuwana) (Rhynchota Pseudo-coccidae) is a highly
polyphagous species widespread in Central Asia, Eastern Europe, USA and other regions.
It is one of the most serious pest of apple, pear and other agricultural crops. Scientific investigations and field tests
demonstrated that 2,6-dimethyl-l,5-heptadien-3-yl acetate is the most attractive one for these species. According to
literature, synthesis of this pheromone suffers from low overall yield (cca 9%), as well as increases the self-cost of this
compound.
Hereby, we report an efficient synthetic route for obtaining of 2,6-dimethyl-l,5-heptadien-3-yl acetate with total
yield more than 60%. |

Investigaţiile şi testările pe teren au demonstrat că cel mai eficient remediu în lupta cu acest dăunător este atractantul 2,6-dimetil-l,5-heptadien-3-acetat. Conform datelor din literatura, sinteza atractantului implică o serie de dificultăţi însoţite de reducerea considerabilă a randamentului totalizant (cca 9%) şi, respectiv, determină mărirea sinecostului acestui produs. În studiul de faţă propunem o cale eficientă şi economicoasă de obţinere a 2,6-dimetil-l,5-heptadien-3-acetatului cu un randament general de peste 60%.</dc:description> <dc:source>Studia Universitatis Moldaviae (Seria Ştiinţe Reale şi ale Naturii) 61 (1) 140-142</dc:source> <dc:subject>attractant</dc:subject> <dc:subject>filed tests</dc:subject> <dc:subject>agricultural crops</dc:subject> <dc:subject>1-Chloro-3-methylbut-2-ene</dc:subject> <dc:subject>2-Methylpropenal</dc:subject> <dc:subject>2</dc:subject> <dc:subject>6-Dimethylhepta- 1</dc:subject> <dc:subject>5-dien-3-ol</dc:subject> <dc:subject>2</dc:subject> <dc:subject>6-Dimethylhepta-1</dc:subject> <dc:subject>5-dien-3-yl acetate</dc:subject> <dc:subject>acetylation</dc:subject> <dc:subject>optimization</dc:subject> <dc:title>Synthesis of 2,6-Dimethylhepta-1,5-Dien-3-Yl Acetate, the pheromone of the Comstock Mealybug Pseudococcus Comstocki </dc:title> <dc:type>info:eu-repo/semantics/article</dc:type> </oai_dc:dc>
