Simultaneous Determination of the Conformation and Relative Configuration of Archazolide A by Using Nuclear Overhauser Effects, J Couplings, and Residual Dipolar Couplings

Combine and conquer: Configurational assignment of remote stereogenic centers in the complex polyketide macrolide archazolide A (see structure; red O, blue N, yellow S) was accomplished by a purely NMR‐based approach relying on a combination of nuclear Overhauser effects, J couplings, and residual dipolar couplings (RDCs).
