An iron-catalyzed acyl-azidation of alkenes under mild reaction conditions has been developed. Aromatic aldehydes or aliphatic aldehydes can be used as the acyl radical precursors; TMSN3 is used as the azido source; TBHP is the initiator. The synthesized unsymmetrical β-azido ketones can be easily transformed into valuable functionalized compounds, such as γ-aminol, γ-azido alcohol, β-azido oxime,
已经开发出在温和的反应条件下烯烃的铁催化的酰基叠氮化。芳族醛或脂族醛可用作酰基自由基前体;优选地,芳族醛或脂族醛可用作酰基前体。TMSN 3被用作叠氮源。TBHP是发起者。合成的不对称β-叠氮基酮可轻松转化为有价值的功能化化合物,例如γ-氨基,γ-叠氮基醇,β-叠氮基肟,β-叠氮基酯和三唑。
