The treatment of arylaminomethyl-substituted donor-acceptor cyclopropanes with a catalytic amount of Yb(OTf) provides expedient access to tetrahydroquinoline derivatives. The transformation proceeds through an intramolecular S2-type attack of the aminomethyl-containing aryl ring on the cyclopropane ring, leading to the formation of the products as single diastereomers.
用催化量的Yb(OTf)处理芳基氨基甲基取代的供体-受体环丙烷可方便地得到四氢喹啉衍生物。该转化过程通过含氨基甲基的芳基环对环丙烷环进行分子内S2型进攻来进行,从而生成单一非对映异构体的产物。
