excitatory amino acid, neodysiherbaine A (2), was isolated as a minor constituent of the aqueous extract from the marine sponge Dysidea herbacea. The structure was deduced by spectroscopic methods and established unambiguously by the total synthesis. The present synthesis, including as a key step cross-coupling of the 6/5-bicyclic core with an amino acid residue, is useful in constructing its structural
[结构:见正文]一种新的兴奋性氨基酸,新dysiherherine A(2),被分离为海洋海绵Dysidea除草剂中水提取物的微量成分。通过光谱方法推导了该结构,并且通过总合成明确地确定了该结构。本发明的合成,包括作为关键步骤的6 / 5-双环核与氨基酸残基的交叉偶联,可用于构建其结构类似物。
