The anticancer natural product simaomicin α has been synthesized. Asymmetric synthesis allowed the assignment of absolute stereochemistry. The enantiomer of the naturally occurring substance shows potent cytotoxicity towards Gram-positive bacteria and human cancer cells. Bn=benzyl, BOM=benzyloxymethyl.
