of tetradenolide, a cytotoxic α-pyrone isolated from Tetradenia riparia, were synthesized stereoselectively using the Z-selective Horner–Emmons reaction followed by acid catalyzed lactonization. Making comparison of the 1H and 13C NMR spectral data of the four diastereomers with those of the reported value of natural product did not lead to determine the relative stereochemistry of the natural tetradenolide
使用Z选择性Horner-Emmons反应立体选择性地合成了四异内酯,这是一种分离自河豚草的细胞毒性α-吡喃酮,是非对映异构体,然后进行酸催化的内酯化反应。将四种非对映异构体的1 H和13 C NMR光谱数据与天然产物的报道值进行比较,并不能确定天然四氢化萘酚的相对立体化学。因此,对相关化合物光谱数据的详细研究导致我们修改了四腺苷的结构,即脱乙酰基硼烷内酯。
