Abstract
Two minor components of solanapyrones D and E, phytotoxins from Altern aria solani, were isolated. The absolute stereochemistry of D and the optical purity of solanapyrones A and D were determined by chemical tr ansformation and measurement of the CD spectrum. In addition, complete signal assignment of the H-1- and C-13-NMR spectra of solanapyrones A and D, and their solution conformations were studied. Feeding experim ents with various isotopically labeled acetates and methionine establi shed the biosynthetic pathway of solanapyrones. The phytotoxicity of s olanapyrones on lettuce seedlings is discussed.
