INSECT PHEROMONES AND THEIR ANALOGS. IV. THE SYNTHESIS OF THE SEX ATTRACTANT OF THE HONEY BEE Apis mellifera

A new and convenient method for the synthesis of 9-oxodec-2E-enoic acid (I) from the readily accessible octa-2E,7-dienyl acetate is proposed.From the latter compound by a series of transformations (oxidation of the terminal double bond to a ketone, saponification, hydrogenation, and oxidation with Corey's reagent) 7-oxooctanal is obtained, and this is condensed by the Knoevenagel reaction with malonic acid to give compound (I) with a yield of 69percent.

INSECT PHEROMONES AND THEIR ANALOGS. XV. THE SYNTHESIS OF 9-OXODEC-2E-ENOIC ACID - A PHEROMONE OF THE HONEYBEE Apis melliferana

A new effective route to the synthesis of 7-oxooctanal has been found which is based on the ozonolysis of the tetrahydropyran-2-yl ether of 7-methyloct-7-en-1-ol - the product of the coupling of the readily available methallyl chloride and the Grignard reagent from the corresponding ether of 5-bromopentan-1-ol.From the 7-oxooctanal has been obtained 9-oxodec-2E-enoic acid - a pheromone of the honeybee Apis melliferana.

Lithiated anions derived from (alkenyl)pentamethyl phosphoric triamides: Useful synthons for the stereoselective synthesis of 9-oxo- and 10-hydroxy-2(E)-decenoic acids, important components of queen substance and royal jelly of honeybee Apis mellifera

Lithiated anions derived from (alkenyl)pentamethyl phosphoric triamides as homoenolate equivalents are used in the reaction with halogenated acetal and ketal giving regioselectively the γ-alkylation adducts. Chemoselective acidic hydrolysis of the enephosphoramide moiety in the presence of acetal or ketal groups leads to expected carbonyl products, key intermediates in the synthesis of natural compounds. The synthetic potential of the presented strategy is illustrated by stereoselective synthesis of two pheromones namely, 9-oxo-2(E)-decenoic acid 1 from queen substance and 10-hydroxy-2(E)-decenoic acid 2 from royal jelly of honeybee Apis mellifera.
