CAL-B (Candida antarctica lipase B) immobilized on an acrylic resin (Novozyme® 435) smoothly catalyzes the aminolysis of methyl esters with propargyl amine furnishing propargyl amides. In the same reaction vessel these propargyl derivatives are consecutively transformed into amide ligated 1,2,3-triazoles in a Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) click reaction in good to excellent yields
固定在丙烯酸树脂(Novozyme®435)上的CAL-B(南极假丝酵母脂肪酶B)可平滑地催化带有炔丙基胺的炔丙基酰胺的甲酯的氨解。在同一反应容器中,这些炔丙基衍生物在Cu(I)催化的叠氮化物-炔烃环加成(CuAAC)点击反应中连续良好地转化为酰胺连接的1,2,3-三唑,其收率良好。
