are a family of alkamide natural products isolated from the pericarps of Zanthoxylum bungeanum (Sichuan pepper), and they are structurally related to the sanshools. While the sanshools, especially hydroxy-α-sanshool, have been studied in a variety of contexts, research regarding the bungeanools has been much more limited. To facilitate their study, we have developed stereoselective syntheses of all
花椒是从花椒果皮中分离得到的一族醇酰胺类天然产物,在结构上与花椒有亲缘关系。虽然 sanshools,尤其是羟基-α-sanshool,已在各种背景下进行了研究,但关于 bungeanools 的研究却非常有限。为了促进他们的研究,我们通过使用也适用于合成类似物的灵活路线开发了该化合物家族所有四个成员的立体选择性合成。合成中的关键转化是立体选择性三苯基膦/苯酚催化的炔酸酯异构化为相应的共轭 E,E-二烯酸酯。
