title: Discovery of metaflumizone, a novel semicarbazone insecticide.
abstract: Metaflumizone, (EZ)-2'-[2-(4-cyanophenyl)-1-(alpha,alpha,alpha-trifluoro-m-tolyl)ethylidene]-4-(trifluoromethoxy) carbanilohydrazide, was discovered by Nihon Nohyaku in the early 1990s and belongs to the new class of semicarbazone insecticides. It is now being globally co-developed as the animal health product, ProMeris((R)), in cooperation with Fort Dodge Animal Health and as an agricultural and consumer insecticide in cooperation with BASF. Metaflumizone was developed in a synthesis program initiated from a pyrazoline insecticide lead. In this paper, we describe the development, discovery and structure activity relationships for metaflumizone and related compounds.
