Resumo:
Abstract Imazethapyr, a recently introduced imidazolinone herbicide, is registered for use on soybeans and other legumes in the United States and Canada. Its maximum allowed residue level in soybeans is 0.1 ppm. A method was developed to allow the measurement of ≥0.01 ppm imazethapyr on soybeans. The method exploits the ready cyclization of the nonvolatile acid to the volatile imidazoisoindol-3,5-dione by using an excess of easily removed, watersoluble carbodiimide and the selectivity of gas chromatography with nitrogen-phosphorus detection. A simple cleanup on a diol-bonded silica minicolumn reduces the complexity of the soybean extract. The derivatization works equally well for other imidazolinone herbicide acids. Because imidazoisoindolediones have characteristic fragmentation patterns, they are useful for mass spectroscopic confirmation of suspected residues.

Resumo:
Depuis quelques décennies, les chimistes cherchent à toujours repousser les limites des stratégies de synthèse en développant des méthodologies toujours plus efficaces, plus simples et plus économes. Dans ce contexte, la fonctionnalisation directe de liaisons C—H catalysée par des métaux de transition constitue l’un des outils les plus puissants pour construire et fonctionnaliser des molécules simples mais aussi des édifices moléculaires de plus en plus complexes, avec une grande diversité de liaisons C—H, ces stratégies répondant également aux besoins actuels d’ouverture de l’espace chimique de fonctionnalisation de façon orthogonale. L’imidazoisoindole, hétérocycle tricyclique composé d’un noyau imidazole, est une plateforme pharmacologique très intéressante et présente des liaisons C—H avec des propriétés très diverses, mais aucune méthodologie de fonctionnalisation tardive de ces structures n’a encore été répertoriée dans la littérature. Ces travaux de thèse s’inscrivent dans ce contexte et présentent, (I) fort de l’expérience passée du laboratoire, une méthodologie robuste de synthèse à grande échelle d’imidazoisoindoles diversement substitués par activation C—H intramoléculaire pallado-catalysée ; (II) une extension des méthodologies standards de fonctionnalisation directe C2—H régiosélective de la série des 1,3-diazoles aux imidazo[5,1-a]isoindoles par catalyse coopérative palladium(0)-cuivre(I) ; (III) une méthodologie de mono-fonctionnalisation directe C(sp³)—H pallado-catalysée de la position benzylique des imidazo[2,1-a]isoindoles ; (IV) une étude préliminaire de la régiosélectivité observée lors de la borylation directe C(sp²)—H irido-catalysée des imidazo[2,1-a]isoindoles
For several decades, chemists constantly seek to push the limits of synthetic strategies by developing ever more efficient and more economical methodologies. In this context, transition metal-catalyzed direct functionalization of C—H bonds is one of the most powerful tools for constructing and funtionalizing simple molecules and ever more complex moieties, with a great diversity of C—H bonds. These strategies also answer the needs for the opening of the chemical space of functionalization. Imidazoisoindole, tricyclic heterocycle composed of an imidazole core, is a very interesting scaffold for biological activity and presents C—H bonds with very diverse properties, but late-functionalization methodology of these structures has yet to be listed in the literature. This work takes place in this context and presents, (I) based on past laboratory experience, a robust methodology to synthetize diversely substituted imidazoisoindoles at high scale by palladium-catalyzed intramolecular C—H activation ; (II) an extension of standard directC2—H functionalization of 1,3-diazole moieties applied to imidazo[5,1-a]isoindoles with a palladium(0)-copper(I) cooperative catalysis ; (III) a new methodology of direct C(sp³)—H palladium-catalyzed mono-functionalization at benzylic position of imidazo[2,1-a]isoindoles ; (IV) a preliminary study of the observed regioselectivity of iridium-catalyzed direct C(sp²)—H borylation of imidazo[2,1-a]isoindoles
