Significance

Bafilomycin A1 was isolated from a Streptomyces griseus sp. sulphurus culture and exhibits broad antibacterial and antifungal activity. In addition, it is a selective V-type ATPase inhibitor. The potency for the treatment of osteoporosis has been evaluated. The focal step of this synthesis is a diastereoselective alkynylation of aldehyde D followed by a formal transhydrogenation to create the C12-C13 double bond.
