1,3,5-Trienes containing a CF3 group have been synthesized stereospecifically in good yield via the palladium-catalyzed cross-coupling of (E)-(3-trifluoromethyl-1,3-butadienyl)di-iso-propoxyborane with vinyl halides. As a synthetic application, a novel CF3-containing nucleoside derivative was synthesized via this methodology.
通过钯催化的(E)-(3-三氟甲基-1,3-丁二烯基)二-异丙氧基硼烷与钯的交叉偶联,以高产率立体定向合成了具有CF 3基团的1,3,5-三烯。卤化物。作为合成应用,通过该方法合成了新型的含CF 3的核苷衍生物。
