Structure and solution-state conformation of botcinolide, a new biologically active metabolite from the fungus Botrytis cinerea

The structure of botcinolide, a new, phytotoxic, trihydroxylated nona-lactone, esterified with 4-hydroxy-2-octenoic acid, has been elucidated using both spectroscopic and chemical techniques. Botcinolide is a metabolite of the mould Botrytis cinerea (UK185RRC).
