Synthesis of dimethyl swazinecate, a principal component of the pyrrolizidine alkaloid swazine, was completed from (S)-(â)-β-citronellal; an X-ray crystallographic analysis of natural swazine confirmed its absolute stereostructure.
以(S)-(α)-β-香茅醛为原料,合成了吡咯里西啶生物碱斯威津酸的主要成分二甲酯斯威津酸;天然斯瓦津的 X 射线晶体分析证实了其绝对立体结构。
