The analysis of a batch of toxic mussels (Mytilus galloprovincialis) from the Northern Adriatic Sea led to the isolation of a novel oxazinin, oxazinin-4. Its structure including the relative stereochemistry has been elucidated through extensive NMR analysis. A synthetic route to oxazinins has been crucial in establishing the absolute stereochemistry of oxazinin-4 and for reassigning the absolute C-2
对来自北亚得里亚海的一批有毒贻贝(Mytilus galloprovincialis)的分析导致分离出一种新型的oxazinin,oxazinin-4。已通过广泛的NMR分析阐明了其结构,包括相对的立体化学。在确定oxazinin-4的绝对立体化学和重新分配先前从有毒贝类中分离并进行立体结构表征的oxazinin-1和-2的绝对C-2构型方面,合成oxazinins的途径至关重要。
