Access this Article
The structures of novel macrolide antibiotics, quinolidomicins A<sub>1</sub>, A<sub>2</sub> and B<sub>1</sub>, were elucidated as shown in Fig. 1 by NMR spectral analysis including a variety of two-dimensional techniques. The quinolidomicins possess a novel 60-membered macrolide ring, which is to our knowledge the largest among natural products.
