What is Ascladiol?

Plain description, key identifiers and synonyms

(E)-ascladiol is a butenolide that is furan-2(5H)-one which is substituted by a hydroxymethyl group at position 4 and a 2-hydroxyethylidene group at position 5 (the 5E isomer). A direct precursor of patulin in cell-free preparations of Penicillium urticae patulin-minus mutants J1 and S11, but not S15. It has a role as a mycotoxin. It is a primary allylic alcohol and a butenolide.
