H. Nakajima et al., SOROKINIANIN - A NOVEL PHYTOTOXIN PRODUCED BY THE PHYTOPATHOGENIC FUNGUS BIPOLARIS-SOROKINIANA, Tetrahedron letters, 35(51), 1994, pp. 9597-9600
Structure of sorokinianin, a novel phytotoxin from an isolate of Bipol
an's sorokiniana was determined to be ylenebicyclo[3.2.1]oct-6'-yl)tet
rahydro-2-furanone predominantly on the basis of 2D NMR. The prelimina
ry incorporation study suggested that this phytotoxin is derived bioge
netically not from a geranylgeranylpyrophosphate through removal of tw
o carbons but from a farnesylpyrophosphate and an additional C-3 unit.
