Abstract

A series of scalarane class sesterterpenes (1-8) have been isolated from an Indonesian sponge, Phyllospongia sp. Their structures were determined by spectroscopic analysis and confirmed by single-crystal X-ray diffraction on compound 1. The absolute stereochemistry of 1 was established by modified Mosher's method.

摘要

从印度尼西亚海绵Phyllospongia sp.中分离出了一系列半日花烷类倍半萜（1-8）。通过光谱分析确定了它们的结构，并通过对化合物1进行单晶X射线衍射得到证实。1的绝对立体化学通过改良的莫舍尔方法确定。
