Structure and synthesis of a new cyclopentenone derivative from Trichodermaalbum

Abstract

A dextrorotatory product isolated from cultures of Trichoderma album has been identified as 5-hydroxy-3-methoxy-5-vinyl-2-cyclopenten-1-one, and a synthesis of the latter in racemic form is described. The possibility that this compound might be an artifact produced during the isolation procedure, rather than a true metabolite, is not excluded.
