An (S,S)-QuinoxP*-supported Cu(i) catalyst has been disclosed for highly enantioselective intramolecular addition of aryl pinacolboronic esters to unactivated ketones under mild reaction conditions. This protocol showcases a broad substrate tolerance and allows access to various chiral 2,3-dihydrobenzofuran-3-ol derivatives in generally good yields with excellent enantioselectivities.
已经公开了在温和的反应条件下,将(S,S)-QuinoxP *负载的Cu(i)催化剂用于高对映选择性分子内将芳基频哪醇硼酸酯加成至未活化的酮上。该方案展示了广泛的底物耐受性,并允许以良好的对映选择性,以通常良好的产率获得各种手性2,3-二氢苯并呋喃-3-醇衍生物。
