stereoselective total synthesis of jomthonic acid A is described. The key features of the synthetic strategy are a Sharpless asymmetric epoxidation, a Gilmann reagent-induced methylation, a Mitsunobu reaction, a Yamaguchi esterification, and an O-(benzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium tetrafluoroborate (TBTU)-mediated amide coupling. Jomthonic acid A is an architecturally rare amino acid containing
描述了乔松酸 A 的立体选择性全合成。该合成策略的关键特征是 Sharpless 不对称环氧化、吉尔曼试剂诱导的甲基化、光信反应、山口酯化和 O-(苯并三唑-1-基)-N,N,N',N'-四甲基脲四氟硼酸盐 (TBTU) 介导的酰胺偶联。Jomthonic acid A 是一种结构上罕见的氨基酸,包含一个 β-甲基苯丙氨酸残基和一个 4-甲基-(2E,4E)-六-2,4-二烯酸酯部分。当针对小鼠 ST-13 前脂肪细胞进行测试时,它显示出抗糖尿病和抗动脉粥样硬化活性。
