A successful synthesis of the acid part of salvianolic acid D is described (eight steps from isovanillin, 22% overall yield). The benzaldehyde key intermediate was obtained in six steps in 52% overall yield and was converted into the trimethylated precursor molecule using the Knoevenagel procedure. Finally, the acid part of salvianolic acid D was obtained by the exhaustive deprotection of the methyl groups with boron tribromide.
本研究成功合成了丹酚酸 D 的酸性部分(从异香兰素开始,分八个步骤合成,总收率为 22%)。苯甲醛关键中间体通过六个步骤获得,总收率为 52%,并通过 Knoevenagel 程序转化为三甲基化前体分子。最后,用三溴化硼对甲基进行彻底脱保护,得到了丹酚酸 D 的酸部分。
