## w : The crystalline spiroketal sub-unit 2 has been synthesized in ten steps from the 2S,3Rdiol2 using a remote partial stereocontrol for the aldolisation step. The unique biological activity of milbemycins and avermectins as well as their challenging structural features (1) led us to develop a
An asymmetric synthesis of the tricyclic spiroketal subunit of the saponaceolides is described in which the absolute stereochemistry at C-2' and C-6' is established through a conformationally and stereoelectronically controlled cyclization ofa dihydroxyketone pyran intermediate.
