Deuterium labeled methacrylates (5,6), tiglates (10,12), and senecioates (13,14,16,17), important for biosynthetic studies on the synthesis of carboxylic acids in carabid beetles, have been prepared using organocopper-alkyne coupling reactions. With 1,1,1-triethoxypropyne as a coupling partner, a novel directing effect was observed; the “branched” product was formed exclusively.
已使用有机铜-炔烃偶联剂制备了氘标记的甲基丙烯酸酯(5,6),tiglates(10,12)和千里光酸酯(13,14,16,17),这对于在甲壳虫中合成羧酸的生物合成研究很重要。反应。以1,1,1-三乙氧基丙炔为偶合剂,观察到了新的导向作用。“分支”产品是专门形成的。
