Copper‐catalyzed allylic alkylation of azoles, a pyridine N‐oxide, and fluoroarenes with secondary allylic phosphates proceeded under mild reaction conditions with excellent γ‐E‐selectivity. The reactions with enantioenriched allylic phosphates proceeded with 1,3‐anti stereoselectivity to generate an allylic stereogenic center at the position α to the aromatic ring.
铜催化的唑类,吡啶N-氧化物和氟代芳烃与仲烯丙基磷酸的烯丙基烷基化反应在温和的反应条件下以优异的γ- E选择性进行。与对映体富集的烯丙基磷酸酯的反应以1,3-抗立体选择性进行,以在芳环的α位生成烯丙基立体异构中心。
