Behavioral responses of Spodoptera littoralis males to sex pheromone components and virgin females in wind tunnel

The major component of the sex pheromone of female Spodoptera littoralis, (Z,E)-9,11-tetradecadienyl acetate (1), elicited all steps of the male behavioral sequence, i.e., wing fanning and taking flight, oriented upwind flight and arrival to the middle of the tunnel, close approach and contact with the source. The activity was equivalent to that elicited by virgin females. In the range of doses tested, the dosage of 1 had no significant effect on the number of source contacts. Male response was significantly affected by light intensity, being optimum at 3 lux. Activity of the minor components (Z)-9-tetradecenyl acetate (2), (E)-11-tetradecenyl acetate (3), tetradecyl acetate (4), (Z)-11-tetradecenyl acetate (5), and (Z,E)-9,12-tetradecadienyl acetate (6) was significantly lower than that of the major component when assayed individually. In multicomponent blends compound 4 appeared to strongly decrease the number of males arrested at the source, the effect being particularly important when compound 5 was present in the blend. Results of single sensillum experiments confirmed the existence of two main physiologically distinct sensillar types. The most common type of sensilla contained a neuron that responded specifically to compound 1. A second type of sensilla, located laterally on the ventral sensory surface, contained two receptor neurons responding to compound 6 and to (Z)-9-tetradecenol. Among short sensilla, one hair responded to compound 4 and could represent a minor sensillar type. No sensory neuron was found to detect the other minor pheromone compounds 2, 3, and 5,.

A "TUNABLE" STEREOSELECTIVE ALKENE SYNTHESIS BY IODODESILYLATION OF VINYLSILANES

The stereoselectivity of iododesilylation of terminal E-vinylsilanes varies with changing amount of Lewis acid.The use of this "tunable" stereoselective reaction was demonstrated by the syntheses of two insect sex pheromones with defined E/Z isomeric rations.

SYNTHESIS OF PHEROMONE DERIVATIVES VIA Z-SELECTIVE OLEFIN METATHESIS

Disclosed herein are methods for synthesizing fatty olefin metathesis products of high Z-isomeric purity from olefin feedstocks of low Z-isomeric purity. The methods include contacting a contacting an olefin metathesis reaction partner, such as acylated alkenol or an alkenal acetal, with an internal olefin in the presence of a Z-selective metathesis catalyst to form the fatty olefin metathesis product. In various embodiments, the fatty olefin metathesis products are insect pheromones. Pheromone compositions and methods of using them are also described.

Preparation of stereochemically pure E- and Z-alkenoic acids and their methyl esters from bicyclo[n.1.0]alkan-1-ols. Application in the synthesis of insect pheromones

Oxidative cleavage of exo- and endo-alkyl- and hydroxyalkyl-substituted bicyclo[n.1.0]alkan-1-ols with (diacetoxy-λ3-iodanyl)benzene gave the corresponding methyl alkenoates exclusively with E or Z configuration of the double bond. This reaction was used as the key stage in the syntheses of stereoisomerically pure components of pest insect pheromones: (E)-dodec-9-en-1-yl acetate (European pine shoot moth Rhyacionia buoliana), (Z)-tetradec-11-en-1-yl acetate (European oak leafroller Tortrix viridana), and (3E,8Z,11Z)-tetradeca-3,8,11-trien-1-yl acetate (tomato leafminer Tuta absoluta).

Concise syntheses of insect pheromones using Z-Selective cross metathesis

Very short synthetic routes to nine cisolefin-containing pheromones containing a variety of functionality, including an unconjugated (E,Z) diene, are reported (see scheme). These lepidopteran pheromones are used extensively for pest control, and were easily prepared using ruthenium-based Z-selective cross metathesis, highlighting the advantages of this method over less efficient ways to form Z olefins.

The present invention is directed to methods of synthesizing insect pheromones, particularly lepidopteran insect pheromones, their precursors and derivatives from inexpensive, readily available starting materials using olefin metathesis catalysis.

Exo- and endohormones. XXIV. 1 a convenient synthesis of (Z)-11-tetradecen-1-YL acetate, component of lepidoptera insect sex pheromone

A new and practical synthesis of (Z)-11-tetradecene-1-yl acetate was developed using commercially raw material. The synthesis was based on a C 10+C2=C12 and C12+C 2=C14 coupling scheme, starting from 1,10-decane-diol. The route involves, as the key step, the use of the mercury derivative of the terminal alkyne ω-functionalised as intermediate, which is lithiated and then alkylated. The first coupling reaction took place between monosodium acetylene obtained in situ and 1-tert-butoxy-10-bromo-decane. The second coupling reaction consisted in directly lithiated of di (t-butoxy-dodec-11-yne) mercury and then alkylated with ethyl bromide obtaining 1-tert-butoxy-tetradec- 11-yne. After acetylation and stereoselective reduction in the presence of NiP-2 catalyst of 1-tertbutoxy- tetradec-11-yne gave (Z)-11-tetradecene-1-yl acetate with 99% isomeric purity.
