| Abstract: | The previously proposed structure for teucrin B [15,16-epoxy -1,7-dihydroxy-cleroda-13(16),14-diene- 18,19:20,12-diolide] must be amended to 15,16-epoxy-2β,6β-dihydroxy-neo-cleroda-13(16), 14-diene-18,19:20,12S-diolide, which corresponds to the structure that has been established for dihydroteugin. |
