7-enynes that contain electron-donating and electron-withdrawing groups on the triple bond has been developed that proceeds through a Sonogashira-type coupling reaction. The ring-closing enyne methathesis (RCEYM) of the obtained 1,7-enynes with commercially available Grubbs and Hoveyda catalysts provides access to a series of new cyclic α-amino acids. The latter compounds that contain the 1,3-diene moiety
已经开发了一种有效的制备新的 α-CF3 α-氨基酸 1,7-烯炔的方法,该方法在三键上含有给电子和吸电子基团,该方法通过 Sonogashira 型偶联反应进行。获得的 1,7-烯炔与市售 Grubbs 和 Hoveyda 催化剂的闭环烯炔复分解 (RCEYM) 提供了获得一系列新的环状 α-氨基酸的途径。后一种含有 1,3-二烯部分的化合物是构建三氟甲基化多环系统的有吸引力的结构单元。
