标题 :Synthesis of pyrethroids and pyrethroid-containing compositions
发明人：COELHO PEDRO; MEINHOLD PETER; CHEN MIKE M Y
权利人:PROVIVI INC
摘要:The present invention provides methods for synthesizing pyrethroid compounds. The methods include forming a first reaction comprising an olefin and an allethrolone-type unsaturated alcohol under conditions sufficient to form a metathesis product and converting the metathesis product to the pyrethroid. Methods of the invention can be used to prepare compounds including pyrethrin I, cinerin I, jasmolin I, pyrethrin II, cinerin II, and jasmolin II as well as other synthetic pyrethroid compounds. Insecticidal compositions and methods for controlling insects are also described.

标题:Process for preparing dihalovinylcyclopropanecarboxylates
发明人：KONDO KIYOSHI; MATSUI KIYOHIDE; NEGISHI AKIRA; TAKAHATAKAE YURIKO
权利人:SAGAMI CHEM RES
摘要:Novel synthesis of dihalovinylcyclopropanecarboxylates, including potent insecticides, are described. The processes begin with the reaction between an alkenol and an orthoester to produce a γ-unsaturated carboxylate, followed by the catalyzed addition of a carbon tetrahalide to the double bond and dehydrohalogenation to produce a cyclopropane derivative.
