当(-)-鹰爪豆碱-Cu(Ⅱ)配合物与三乙胺组配,以甲醇为溶剂,反应在0~5℃下进行时,催化活性及立体选择性最佳,但催化剂用量需高达20%。
When the reaction was carried out in methanol under 0 ℃ with ( - ) - sparteine-copper ( II ) complex and triethylamine as the double catalytic activation system , best catalytic activity and enantioselectivity were achieved , but the required catalyst load was up to 20mol % .
