Toward the Synthesis of Reidispongiolide A: Stereocontrolled Synthesis of the C<sub>17</sub>−C<sub>22</sub> and C<sub>23</sub>−C<sub>35</sub> Degradation Fragments
reactions of chiral ketones, a highly stereocontrolled synthesis of each of the C(17)-C(22) and C(23)-C(35) degradation fragments of reidispongiolide A has been achieved. This permits a configurationalassignment of the complete C(17)-C(36) region of this antimitotic macrolide, along with providing advanced intermediates for a projected total synthesis.
