Stereoselective synthesis of the C23−C34 fragment of symbiodinolide, which possesses the originally proposed stereochemistry, and its diastereomers was achieved in 19 steps from l-aspartic acid, respectively. Comparison of spectroscopic data of the synthetic products with those of the degraded product of symbiodinolide led to a structural revision of the C23−C34 fragment.
具有最初提出的立体化学的共生双嘧啶的C23-C34片段的立体选择性合成及其非对映异构体分别由1-天冬氨酸分19步完成。合成产物与共生物素的降解产物的光谱数据的比较导致了C23-C34片段的结构修改。
