Chemistry of insect antifeedants from Azadirachta indica (Part 8):1 Synthesis of hydroxydihydrofuran acetal fragments for biological evaluation and azadirachtin total synthesis studies

The work describes a unified strategy towards the preparation of model hydroxydihydrofuran acetal fragments (2) (3) and (45) common to the potent insect antifeedant and growth disruption agent azadirachtin (1). These units, along with other analogues, wer
