class i yanuthone
Any of the yanuthones whose 5,6-epoxycyclohex-2-en-1-one core is substituted at position 3 by a methyl group or its oxidised (hydroxymethyl or acyloxymethyl) derivatives. It is thought that the core may be derived from 6-methylsalicylic acid, resulting in a C<small><sub>7</sub></small> scaffold through a decarboxylation.
