The isolation and characterization of polivione, a polyketide metabolite and probably a precursor of citromycetin (1), from Penicillium frequentans is reported. The structure elucidation of polivione is based on a detailed study of its high-field 1H and 13C n.m.r. spectra. Extensive use was made of two-dimensional homonuclear and heteronuclear correlation experiments in the assignment of the n.m.r
据报道,从青霉中分离并鉴定了聚维酮,一种多酮化合物代谢物和可能是柠檬菌素的前体(1)polivione 。polivione的结构阐明是基于对其高场1 H和13 C nmr光谱的详细研究。二维同核和异核相关实验在nmr光谱的分配中得到了广泛使用。还研究了一些化学转化,以确认其结构并研究其与柠檬霉素的关系。
