for metals were prepared by copper-catalyzed coupling (CLICK reaction) of 2-ethynylpridine, 2-ethynyl-5-nitropyridine, 2-ethynylquinoline, and 2,6-diethynylpyridine with 12 protected glycosyl azides in the gluco and galacto series and 2 benzyl azides. The 1,2,3-triazole-linked glycoconjugates prepared were used as ligands for the copper-catalyzed addition of phenylacetylene to N-benzylideneaniline to
摘要 通过2-乙炔基吡啶,2-乙炔基-5-硝基吡啶,2-乙炔基喹啉和2,6-二乙炔吡啶与十二种保护的糖基叠氮化物的铜催化偶联(CLICK反应),制备了一系列30种金属的双齿和三齿配体在葡萄糖和半乳糖系列中和2个苄基叠氮化物。制备的1,2,3-三唑连接的糖缀合物用作配体,用于铜催化的苯乙炔加成到N-亚苄基苯胺上,得到手性N-(1,3-二苯基丙-2-炔-1-基)苯胺。 通过2-乙炔基吡啶,2-乙炔基-5-硝基吡啶,2-乙炔基喹啉和2,6-二乙炔吡啶与十二种保护的糖基叠氮化物的铜催化偶联(CLICK反应),制备了一系列30种金属的双齿和三齿配体在葡萄糖和半乳糖系列中和2个苄基叠氮化物。制备的1,2,3-三唑连接的糖缀合物用作配体,用于铜催化的苯乙炔加成到N-亚苄基苯胺上,得到手性N-(1,3-二苯基丙-2-炔-1-基)苯胺。
