title: Structural Confirmation of Cotylenin A, a Novel Fusicoccane-diterpene Glycoside with Potent Plant Growth-regulating Activity from Cladosporium Fungus sp. 501-7W.
abstract: The structure of cotylenin A, a potent plant-growth stimulant with the most complex molecule in cotylenins from Cladosporium fungus sp. 501-7W, was analyzed again by HMBC experiments and X-ray crystallography of its diacetyl-dihydroderivative. The previously proposed stereostructure of cotylenin A was thus completely confirmed.
