The absolute stereochemistry of the C-4 ∼ C-17 fragment of theonezolides was establsihed as 8S, 10R, 14S, 16S on the basis of synthesis of the two diastereomers (4a and 4b) suggested from model studies and comparison of their spectral and optical data with those of natural specimen (4) obtained from ozonolysis of 1 ∼ 3.
在模型研究和比较的基础上提出了两种非对映体(4a和4b)的合成基础上,酮内酯的C-4〜C-17片段的绝对立体化学被确立为8 S,10 R,14 S,16 S。它们的光谱和光学数据与臭氧分解1〜3获得的天然样品(4)的光谱和光学数据一致。
