An efficient general methodology for the synthesis of 4-quinolinyl ethers is demonstrated via a highly reactive SNAr reaction of 4-quinolinyl sulfones with a range of structurally diversified 1°, 2°, and 3° alcohols with a wide substrate scope and high yields. By adapting this methodology, a convergent synthesis of a complex target of HCV NS3/4a protease inhibitor BI 201420 was accomplished.
通过4-喹啉基砜与一系列结构多样的1°,2°和3°醇的高反应性S N Ar反应,证明了合成4-喹啉基醚的有效通用方法,该方法具有广泛的底物范围和较高的产量。通过采用这种方法,可以完成HCV NS3 / 4a蛋白酶抑制剂BI 201420复杂靶标的融合合成。

Microwave-Assisted Metal- and Ligand-Free O-Arylation of Quinolones Using Diaryliodonium Salts: An Easy and Rapid Synthesis of Aryloxyquinolines
A microwave-assisted metal- and ligand-free direct O-arylation of quinolones has been achieved by employing easily accessible diaryliodonium salts in the presence of a base to afford various aryloxyquinolines in good yields. The operationally simple and rapid protocol has also been utilized for the construction of biologically important benzofuro[3,2-c]quinolines.
