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.

New approach to the synthesis of 9-oxo-2E-decenoic acid, a multifunctional pheromone of queen honeybee, from the telomer of butadiene and water

A new approach was proposed for the synthesis of 9-oxo-2E-decenoic acid, a multifunctional pheromone of queen honeybee (Apis mellifera L.), starting from the available telomer of butadiene and water (2E,7-octadien-1-ol) using in the key steps partial ozonolysis of the corresponding carbonyl compound, selective oxidation of the conjugated aldehyde into a carboxylic acid, and alkylation of acetoacetic ester to introduce the oxo group.

A two-step synthesis of the 'Queen substance' of the honey bee

A synthesis of the 'queen substance' was accomplished in two steps from readily available starting materials. The key step was a novel one-pot reduction of 7-oxooctanoic acid to 7-oxooctanal followed by condensation with malonic acid.

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.

Practical synthesis of (E)-α,β-unsaturated carboxylic acids using a one-pot hydroformylation/decarboxylative Knoevenagel reaction sequence

Combining the regioselective room temperature/ambient pressure hydroformylation and a modification of the Doebner-Knoevenagel reaction allowed for the development of an efficient, one-pot procedure for the synthesis of (E)-α,β-unsaturated carboxylic acids. The reaction proceeds under mild conditions, tolerates a variety of functional groups and gives (E)-α,β-unsaturated carboxylic acids in good yields and with excellent regio-and stereocontrol. The practicability of this process has been demonstrated by a short protecting group-free synthesis of the queen honeybee pheromones 9-ODA[( E)-9-oxodec-2-enoic acid] and 9-HDA[( E)-9-hydroxydec-2-enoic acid].

Synthesis of a multifunctional pheromone of the honeybee Apis mellifera via condensation of 7-oxooctanal with malonic acid

Condensation of 7-oxooctanal with malonic acid in a Doebner reaction produces 9-oxo-2E-decenoic acid (42% yield) and a comparable amount of products from Tishchenko disproportionation of the starting aldehyde (7-oxooctyl-7- oxooctanoate) and re-esterification by acetic acid (7-oxooct-1-ylacetate and 7-oxooctanoic acid).
