The enantioselective total synthesis of the potent antiparasitic agent milbemycin D (1) has been achieved. The spiroketal fragment is prepared through a novel spiroketalization of a hydroxy pyrone to set the anomeric stereocenter and establish functionality for the stereocontrolled attachment and subsequent extension of the connecting chain between the spiroketal and the hexahydrobenzofuran fragment
