Two new chlorinated phenyloxazole glycosides, named rosellosides A () and B (), were isolated from the endophytic fungus sp. Glinf021, which was derived from the medicinal plant (Leguminosae). Both compounds were rare chlorinated polyketide glycosides bearing an oxazole moiety. Their structures were elucidated by analysis of the NMR and HRESIMS data, and their absolute configurations were determined by quantum chemical ECD calculations and X-ray crystallography.
从药用植物（豆科）来源的内生真菌sp. Glinf021中分离出两种新的氯化苯基恶唑糖苷，命名为玫瑰糖苷A（）和B（）。这两种化合物都是带有恶唑部分的罕见氯化聚酮糖苷。通过对核磁共振（NMR）和高分辨电喷雾电离质谱（HRESIMS）数据的分析阐明了它们的结构，并通过量子化学电子圆二色光谱（ECD）计算和X射线晶体学确定了它们的绝对构型。
