Abstract

We report on the chemical characteristics of the red alga , collected off the coast of Yoshio, Katsuura, Boso Peninsula, Japan. We isolated two new brominated C-acetogenins in this species, which we name katsuurenyne A () and katsuurenyne B (), along with two already known halogenated terpenes [2,10-dibromo-3-chloro-α-chamigrene () and aplysiadiol ()]. We extensively analysed spectral data (from IR, ESI-MS, 1D-NMR and 2D-NMR) to confirm the structure of these compounds.

摘要

我们报告了在日本房总半岛胜浦市吉良海岸采集的红藻的化学特征。我们从该物种中分离出两种新的溴化 C-乙酸盐，分别命名为 katsuurenyne A () 和 katsuurenyne B (), 以及两种已有的卤代萜烯[2,10-二溴-3-氯-α-菖蒲烯 () 和 aplysiadiol ()]。我们广泛分析了光谱数据（IR、ESI-MS、1D-NMR 和 2D-NMR）以确认这些化合物的结构。
