Symmetry helps: The totalsynthesis of the potent actin‐targeting C2‐symmetric myxobacterial macrolide rhizopodin (see scheme) is accomplished by the convergent assembly of three building blocks of similar complexity, a concise macrocyclization strategy, and a late‐stage introduction of the labile side chains.

A convergent synthesis of the central C8–C22 core of the potent macrolide antibiotic rhizopodin is reported. Notable features of the stereocontrolled approach include an asymmetric reverse prenylation of an alcohol using a method of Krische, a thiazolium catalyzed transformation of an epoxyaldehyde as described by Bode, and a late-stage oxazole formation from advanced intermediates. This route demonstrates
