An enolate‐mediated organocatalytic azide–ketone [3+2]‐cycloaddition (OrgAKC) reaction of a variety of enolizable arylacetones and deoxybenzoins with aryl azides was developed for the synthesis of fully decorated 1,4‐diaryl‐5‐methyl(alkyl)‐1,2,3‐triazoles in excellent yields with high regioselectivity at 25 °C for 0.5–6 h. This reaction has an excellent outcome with reference to reaction rate, yield
烯醇介导的有机催化叠氮化物-酮[3 + 2]-环加成(OrgAKC)反应由多种可烯醇化的丙酮和脱氧安息香素与叠氮化物开发,用于合成完全装饰的1,4-二芳基-5-甲基(烷基) ‐1,2,3-三唑在25°C下保持0.5–6 h时具有极高的选择性,并具有较高的区域选择性。该反应在反应速率,产率,区域选择性,操作简便性以及底物和催化剂的可用性方面具有优异的结果。该反应比以前已知的金属介导反应更具优势。
