Two minor components of solanapyrones D and E, phytotoxins from Alternaria solani, were isolated. The absolute stereochemistry of D and the optical purity of solanapyrones A and D were determined by chemical transformation and measurement of the CD spectrum. In addition, complete signal assignment of the (1)H- and (13)C-NMR spectra of solanapyrones A and D, and their solution conformations were studied
solanapyrones D和E的两个次要成分,即来自Alternaria solani的植物毒素被分离出来。D的绝对立体化学和茄吡喃酮A和D的光学纯度通过化学转化和CD光谱的测量来确定。此外,研究了茄吡喃酮A和D的(1)H-和(13)C-NMR谱的完整信号分配,以及它们的溶液构象。各种同位素标记的乙酸盐和蛋氨酸的进料实验建立了茄那隆的生物合成途径。讨论了茄胺酮对生菜幼苗的植物毒性。
