H. Nakajima et al., COCHLIOSPICIN-A - A NEW METABOLITE RELATED TO SPICIFERINONE, A PHYTOTOXIN OF THE FUNGUS COCHLIOBOLUS-SPICIFER, Journal of natural products, 60(4), 1997, pp. 414-416
The structure of cochliospicin A, a new metabolite biogenetically rela
ted to a phytotoxin, spiciferinone, produced by Cochliobolus spicifer
was determined to be (3R,4S*,6S*,7R*,3'R*)-7-ethyl-5 ione-6-spiro-5'-
(3'-hydroxytetrahydrofuran-2'-one) (1) by X-ray analysis.
