N-Oxydihydropyrrole derivatives were synthesized through an intramolecular Claisen condensation reaction. The N-acylation of hindered hydroxylamines played a key role in providing the useful intermediates, which could be converted to a variety of N-oxydihydropyrrole derivatives.

A new series of N-oxydihydropyrrole derivatives was synthesized and evaluated for insecticidal activity against Nilaparvata lugens and Myzus persicae. Various substituents were introduced to the 1-position of the dihydropyrrole ring, and the derivatives obtained exhibited systemic and/or contact insecticidal activity. The structure-activity relationship revealed that small alkyoxy and alkoxyalkoxy groups were more favorable than alkylcarbonyloxy, alkoxycarbonyloxy, or sulfonyloxy groups as substituents at the 1-position.
