The asymmetric allylboration of aldehydes with pinacolallylboronates catalyzed by 1,1′-spirobiindane-7,7′-diol (SPINOL) based phosphoric acids is described. 6,6′-Bis(2,4,6-triisopropylphenyl)SPINOL-based phosphoric acid was found to be a general, highly enantioselective catalyst for such allylboration reactions and excellent enantioselectivities were obtained for different types of aldehydes including
描述了由基于 1,1'-spirobiindane-7,7'-二醇 (SPINOL) 的磷酸催化的醛与频哪醇基硼酸酯的不对称烯丙基硼化反应。6,6'-双(2,4,6-三异丙基苯基)SPINOL 基磷酸被发现是此类烯丙基硼化反应的通用、高对映选择性催化剂,并且对不同类型的醛(包括芳香醛、α、 β-不饱和醛、炔丙醛和脂肪醛。
