obscurum from Tarifa Island (Cádiz, Spain) has led to the characterization of six new unsaturated 2-amino-3-ol compounds, the obscuraminols A-F. Five of them, the obscuraminols B–F, were isolated as their corresponding diacetyl derivatives. Their structures were established by spectroscopic analysis, their relative configurations by NOEDS study of oxazolidinone derivatives, and their absolute configurations
来自塔里法岛(西班牙加的斯)的海鞘假单胞菌的研究导致了六种新的不饱和2-氨基-3-醇化合物(暗味胺基AF)的表征。其中五种为暗疮胺基B-F,作为其相应的二乙酰基衍生物被分离出来。通过光谱分析确定它们的结构,通过对恶唑烷酮衍生物的NOEDS研究确定它们的相对构型,并且通过将Mosher方法应用于N-乙酰基衍生物来确定它们的绝对构型。
