The new natural products (+)-curcutetraol and (−)-curcutriolamide were isolated from the bacterium CNH-741 and the fungus CNC-979, isolated from marine sediment. (+)-Curcutetraol is a polar compound and contains a tertiary benzylic alcohol moiety at the single stereogenic center, which was retained without racemization by avoiding chromatography on silica. The absolute configuration of (+)-curcutetraol
新的天然产物 (+)-curcutetraol 和 (-)-curcutriolamide 从细菌 CNH-741 和真菌 CNC-979 中分离出来,从海洋沉积物中分离出来。(+)-Curcutetraol 是一种极性化合物,在单个立体中心含有叔苄醇部分,通过避免在硅胶上进行色谱,保留而没有外消旋化。(+)-curcutetraol 的绝对构型是通过将其实验 CD 光谱与量子化学 CD 计算预测的光谱进行比较来确定的。来自海洋来源的酚类红没药烷倍半萜类化合物以前仅从柳珊瑚和海绵中获知。已开发出外消旋姜黄醇的短程全合成。(© Wiley-VCH Verlag GmbH & Co.
