The ortho-lithiation of N-Boc protected 3-aminofuran was investigated. Directed lithiation followed by quenching with an appropriate electrophile led to new 2,3-disubstituted furans. Halogenated compounds obtained by this methodology represent useful intermediates for subsequent cross-coupling reactions.
对N-Boc保护的3-氨基呋喃进行了正位锂化研究。定向锂化后,用适当的电亲体淬灭,得到了新的2,3-二取代呋喃。通过这种方法获得的卤化化合物代表了后续交叉偶联反应的有用中间体。
