X-Ray crystallographic structure determination of detigloyldihydroazadirachtin and reassignment of the structure of the limonoid insect antifeedant azadirachtin
Abstract
The structure of detigloyldihydroazadirachtin (tigloyl = 2-methylcrotonoyl) has been determined by single-crystal X-ray diffraction methods and for the first time permits unambiguous structure assignment of the limonoid insect antifeedant azadirachtin.
