hydroxydihydrofuran acetal fragments (2) (3) and (45) common to the potent insectantifeedant and growth disruption agent azadirachtin (1). These units, along with other analogues, were prepared for biological evaluation as antifeedants. Furthermore, several potential coupling fragments (51), (52), (54), (55), (62), (63) and (56) for azadirachtinsynthesis were also prepared from common precursors. Methods
