2-Alkenoyl pyridine N-oxides are introduced as a new kind of efficient dienophiles for the Cu(II)-bis(oxazoline) (BOX) catalyzed enantioselective Diels-Alder reaction affording higher reactivity and enantioselectivity (ee's up to 96%) than the corresponding nonoxidized 2-alkenoyl pyridines.
2-烯丙酰基吡啶氮氧化物被引入作为一种新型高效亲双烯体,用于铜(II)-双(恶唑啉)(BOX)催化的对映选择性狄尔斯-阿尔德反应,与相应的未氧化的2-烯丙酰基吡啶相比,具有更高的反应活性和对映选择性(对映体过量高达96%)。
