## Abstract ^1^H NMR spectroscopy was used to determine the conformations of the aminoglycoside antibiotic __N__‐demethylclindamycin and two of its cyclic derivatives. The conformational features of these systems were determined by consideration of vicinal coupling constants and, in some cases, nuc
