Synthesis of the C21-C34 fragment of antascomicin B
by Hutchison, John M.; Gibson, Andrew S.; Williams, David T.; McIntosh, Matthias C.
The C21-C34 fragment of the potent FKBP12-binding macrolide antascomicin B was prepared using Ireland-Claisen and allylic diazene rearrangements to establish the C26/C27 and the C23 stereocenters, respectively. Directed hydrogenation installed the C29 beta-configuration. The fragment possesses 7 of the 11 fixed stereocenters contained in the natural product.
