Stereoselective synthesis of 11(E)-tetradecen-1-yl acetate-Sex pheromone of sod webworm (Loxostege sticticalis)

On the basic of Claisen rearrangement using orthoesters we carried out stereoselective synthesis of 11(E)-tetradecen-1-yl acetate, a sex pheromone of sod webworm (Loxostege sticticalis), which is a specially dangerous pests of crops.

SYNTHESIS OF PHEROMONES AND RELATED MATERIALS VIA OLEFIN METATHESIS

Methods for preparation of olefins, including 8- and 11-unsaturated monoenes and polyenes, via transition metathesis-based synthetic routes are described. Metathesis reactions in the methods are catalyzed by transition metal catalysts including tungsten-, molybdenum-, and ruthenium-based catalysts. The olefins include insect pheromones useful in a number of agricultural applications.

SYNTHESIS OF Z-OLEFIN-CONTAINING LEPIDOPTERAN INSECT PHEROMONES

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.

Production of pheromones and fragrances from substituted and unsubstituted 1-alken-3yl alkylates

Compounds of the formula (I) wherein R2 is a branched or unbranched, saturated or ethylenically mono or di unsaturated aliphatic radical, Z is —CH2OH, —CH2OAc or —CHO, m is a whole positive integer of one or more, and Ac is an acetyl group are synthesized by a process wherein a 1-alken-3-yl alkylate, is reacted with a halo alkanol Grignard reagent.

Synthesis of (Z/E)-11-tetradecen-1-ol, a component of Ostrinia nubilalis sex pheromone

11-Tetradecen-1-ol acetate is a mixture of geometric isomers with the Z/E-conformations in a 94:6 ratio that is used as an attractant to trap corn pests. It has a powerful attractive action similar to that of an isomeric mixture of 11-tetradecenyl acetate with the Z/E-conformation in a 95:5 ratio that was extracted from the peritoneal cavity of male Ostrinia nubilalis Hubner in Xinjing (PRC).

Process for preparing functional group-containing olefinic compounds

A process for preparing functional group-containing olefinic compounds comprises the steps of (a) reacting at least one alkylidene phosphorane with at least one carbonyl-containing compound that comprises at least one group that is a leaving group, or that is capable of subsequent conversion to a leaving group, to form an olefinic compound that comprises at least one leaving group, the carbonyl-containing compound being selected from the group consisting of ketones and aldehydes; and (b) reacting the olefinic compound with at least one functional group-containing nucleophile to form a functional group-containing olefinic compound.

Metathesis syntheses of pheromones or their components

The present invention relates to metathesis syntheses for insect sex-attractant pheromones or their components, such as E-5-decenyl acetate, the major component of the Peach Twig Borer pheromone; (5R,6S)-6-acetoxy-5-hexadecanolide, the mosquito oviposition attractant pheromone; E9,Z11-hexadecadienal, the pecan nut casebearer moth pheromone; 9-tetradecenyl formate, an analog of the Diamondback Moth (DBM) pheromone; 11-tetradecenyl acetate, the Omnivorous Leafroller (OLR) pheromone; E-4-tridecenyl acetate, the major component of the Tomato Pinworm (TPW) pheromone; E,E-8,10-dodecadienol, the Codling Moth (CM) pheromone. The syntheses preferably employ a Class I-IV metathesis catalyst, entail few reaction steps, use generally commercially available starting materials, and have relatively short process times. These syntheses produce good yields without the need for expensive or sophisticated equipment. The invention also provides an inexpensive route for producing omega-haloalkenols by cross-metathesizing alpha-omega-diacetoxy alkenes and alpha-omega-dihalides to yield omega-haloalkenols, which are easily converted into omega-haloalkanols under traditional hydrogenation methods.

Synthesis of 5-decenyl acetate and other pheromone components

The present invention relates to syntheses of 5-decenyl acetate, the major component in Peach Twig Borer pheromone, and other pheromone components. The syntheses entails few reaction steps, use commercially available starting materials, and have relatively short process times. A preferred embodiment of the syntheses involves self-metathesizing 1-hexene in the presence of Grubbs' catalyst, [(PCy3)2Cl2]Ru═CHPh. The resulting 5-decene is then reacted with an alcohol or acetate protected hexene under vacuum to yield 5-decenyl acetate. These syntheses produce good yields without the need for expensive or sophisticated equipment.

Stereospecific synthesis of 11E-tetradecenal, 11E-tetradecen-1-ol, and its acetate, pheromone components of insects of Lepidoptera order, from 10-undecenoic acid

A regio-and stereospecific synthesis of 11E-tetradecen-1-ol and its derivatives, which are pheromone components of many insect species of Lepidoptera order, by means of a reaction of methylmagnesium cuprate reagent with 1,12-tridecadien-3-yl acetate by the SN2' mechanism, was carried out.
