Anditomin is an oxygenated meroterpenoid produced by Aspergillus stellatus or Aspergillus variecolor.

Aspergillus variecolor produces anditomin from 3,5-dimethylorsellinic acid and farnesyl pyrophosphate using 12 enzymes. The enzyme AndA firstly dehydrogenates one ring of preandiloid B to make preaniloid C. Next it causes a complex ring isomerisation to make anditomin.
