The synthesis and photocleavage of quinolinyl methyl ether-protected alcohols is reported in this study. A variety of quinoline methyl chlorides were synthesized, and protection of the various alcohols was performed via a substitution reaction in the presence of a strong base. Photocleavage of the quinolinyl methyl ether moiety proceeded under visible light with the formation of the charged quinolinyl
这项研究报道了喹啉基甲基醚保护的醇的合成和光解。合成了多种喹啉甲基氯,并在强碱存在下通过取代反应对各种醇进行了保护。喹啉基甲基醚部分的光裂解在可见光下进行,在光敏剂染料的存在下,通过单电子转移形成带电荷的喹啉基自由基中间体,从而以极好的收率得到脱保护的醇。在这项研究中还研究了三乙胺作为牺牲性还原剂和d-山梨醇作为自由基清除剂的效用。
