Abstract: In one aspect, the invention provides a method for synthesizing a fatty olefin derivative. The method includes: a) contacting an olefin according to Formula I
with a metathesis reaction partner according to Formula IIb
in the presence of a metathesis catalyst under conditions sufficient to form a metathesis product according to Formula IIIb:
and
b) converting the metathesis product to the fatty olefin derivative. Each R1 is independently selected from H, C1-18 alkyl, and C2-18 alkenyl; R2b is C1-8 alkyl; subscript y is an integer ranging from 0 to 17; and subscript z is an integer ranging from 0 to 17. In certain embodiments, the metathesis catalyst is a tungsten catalyst or a molybdenum catalyst. In various embodiments, the fatty olefin derivative is a pheromone. Pheromone compositions and methods of using them are also described.-

Abstract: Systems and methods for managing resistance to insecticidal traits and chemicals are provided. In one aspect, systems and methods are provided that: 1) delay the development of resistance to transgenic insecticidal crops and/or chemical insecticides (preemptive strategies), and 2) rescue one or more pests' susceptibility to transgenic insecticidal crops and/or chemical insecticides once pest resistance has developed (responsive strategies).

Abstract: The present application relates to recombinant microorganisms useful in the biosynthesis of unsaturated C6-C24 fatty alcohols, aldehydes, and acetates which may be useful as insect pheromones, fragrances, flavors, and polymer intermediates. The C6-C24 fatty alcohols, aldehydes, and acetates described herein may be used as substrates for metathesis reactions to expand the repertoire of target compounds and pheromones. The application further relates to recombinant microorganisms co-expressing a pheromone pathway and a pathway for the production of a toxic protein, peptide, oligonucleotide, or small molecule suitable for use in an attract-and-kill pest control approach. Also provided are methods of producing unsaturated C6-C24 fatty alcohols, aldehydes, and acetates using the recombinant microorganisms, as well as compositions comprising the recombinant microorganisms and/or optionally one or more of the product alcohols, aldehydes, or acetates.

Abstract: 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.
