Lithiation of polymer-bound 3-furanmethanol and 3-thiophenemethanol followed by the addition of electrophiles and resin cleavage afforded 2,4-disubstituted furans and thiophenes respectively in good yield. The 2,4-substituted thiophene can also be further lithiated on solid-phase at C-5 to give 2,3,5-substituted thiophenes.
聚合物连接的3-呋喃甲醇和3-噻吩甲醇先进行锂化,然后加入电亲体并裂解树脂,分别获得了产率良好的2,4-取代呋喃和噻吩。2,4-取代的噻吩还可以在固相条件下进一步在C-5位锂化,生成2,3,5-取代噻吩。
