摘要:
The present invention provides methods by which trans-(1R,2S)-2-(3,4-difluorophenyl)-cyclopropylamine and related cyclopropane compounds are prepared using synthetic strategies that include a biocatalytic cyclopropanation step.
摘要:
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.
摘要:
The invention provides a method for synthesizing a fatty olefin derivative. In some embodiments, the method includes: a) contacting an unsaturated olefin with an unsaturated fatty acid ester in the presence of a metathesis catalyst under conditions sufficient to form a metathesis product and b) converting the metathesis product to the fatty olefin derivative. In certain embodiments, the metathesis catalyst is a tungsten catalyst or a molybdenum catalyst. In various embodiments, the fatty olefin derivative is an insect pheromone. Pheromone compositions and methods of using them are also described.
