Stereocontrolled total synthesis of (+)-concanamycin F: The strategic use of boron-mediated aldol reactions of chiral ketones

A highly stereocontrolled total synthesis of the 18-membered macrolide (+)-concanamycin F, a potent inhibitor of vacuolar ATPases, is described that proceeds in 5.8% yield over 26 steps. The three key fragments, C1-C13 vinyl iodide, C14-C22 vinyl stannane

Studies in macrolide synthesis: Stereocontrolled synthesis of a C1-C13 segment of concanamycin A

The C1-C13 segment 6 of concanamycin A (1) was prepared by a highly stereocontrolled route (87% overall ds) in 16 steps from the ester 9. Key steps are the one-pot aldol/reduction, 8 → 12, and the HWE reaction, 18 + 19 → 6.
