Oxatropanes from oxiranes: An expedient assembly of the compactplatensimycincore is described. The synthetic approach relies on a Suzuki cross‐coupling, a late‐stage dearomatization reaction, and a copper‐catalyzed vinyl oxirane ring expansion for accessing the oxatropane moiety of the natural product.
