YM-47522 (1) was isolated from the fermentation broth of Bacillus sp. YL-03709B as an antifungal antibiotic. The structure of 1 was elucidated by spectroscopic analyses. YM-47522 (1) consisted of C13 carboxylic acid amide and cinnamate moieties. The relative stereochemistry was also proposed on the basis of chemical transformation into a 1,3-diol acetonide and its NMR data.
从芽孢杆菌属的发酵液中分离出YM-47522(1)。YL-03709B作为抗真菌抗生素。通过光谱分析阐明了1的结构。YM-47522(1)由C 13羧酸酰胺和肉桂酸酯部分组成。还基于化学转化成1,3-二醇丙酮化物及其NMR数据提出了相对立体化学。
