Abstract

Two new stereoisomers of laurane-derived brominated sesquiterpenes, 4-bromolaur-11-en-1,10alpha-diol (1) and 4-bromolaur-11-en-1,10beta-diol (2), one new natural product, laur-11-en-1,10alpha-diol (3), together with 11 known compounds (4-14) were isolated and identified from the organic extract of the marine red alga Laurencia tristicha. Their structures and relative stereochemistry were established by analysis of mass and NMR spectroscopic techniques.

摘要

从海洋红藻三叉劳伦氏藻的有机提取物中分离并鉴定出两种新的月桂烷衍生溴化倍半萜立体异构体，4-溴月桂-11-烯-1,10α-二醇（1）和4-溴月桂-11-烯-1,10β-二醇（2），一种新的天然产物月桂-11-烯-1,10α-二醇（3），以及11种已知化合物（4-14）。通过质谱和核磁共振光谱技术分析确定了它们的结构和相对立体化学。
