Catalytic enantioselective Claisen rearrangement was drastically enhanced under microwave irradiation conditions without any loss of the enantioselectivity. Based on Arrhenius plots it was revealed that enantioselectivity decreased as the internal reaction temperature increased. Therefore, this reaction acceleration would NOT be caused by only a simple thermal effect.
在微波辐射条件下,催化对映选择性克莱森重排反应得到了极大的增强,而对映选择性没有任何损失。根据阿伦尼乌斯图,发现对映选择性随着内部反应温度的升高而降低。因此,该反应加速将不会仅由简单的热效应引起。
