four-component reaction and an intramolecular nucleophilic aromatic substitution (SNAr) has been developed for the rapid access to biaryl-ether containing macrocycles. In the course of this study, we documented that ammonium chloride can promote the Ugi-4CR in non-polar aprotic solvent (toluene) without the interference of an alternative Passerini reaction. Solid phase synthesis of macrocycles by this two-step
涉及的Ugi四组分反应和分子内的亲核芳香取代(S两步序列Ñ AR)已被开发为快速访问包含大环化合物的二芳基-醚。在本研究过程中,我们记录了氯化铵可在非极性非质子传递溶剂(甲苯)中促进Ugi-4CR,而不会受到其他Passerini反应的干扰。还使用聚合物(Wang树脂)负载的α-(4'-氟-3'-硝基)苯乙基异氰基乙酸酯作为输入之一,开发了通过此两步序列的大环化合物的固相合成。
