Investigation of the New Zealand basidiomycete Favolaschia calocera: Revision of the structures of 9-methoxystrobilurins L and L, strobilurin D, and hydroxystrobilurin D

Article abstract of DOI:10.1016/S0040-4039(97)01758-9

9-Methoxystrobilurin K has been obtained from Favolaschia calocera. The previously proposed epoxyprenyl structure for 9-methoxystrobilurin K 2c and dioxan structure for 9-methoxystrobilurin L 3 have both been revised to the prenyldioxepin structure 1a. The epoxyprenyl structures of strobilurin D 2a and hydroxystrobilurin D 2c should also be revised.
