The manganese(III)-based oxidative cyclization of 1,1-diarylethenes 1 with 3-(2-oxoethyl)piperidine-2,4-diones 2 was carried out in acetic acid at reflux temperature to selectively produce azadioxa[4.3.3]propellanes 3 in high yields. A similar cyclization with the 2-(2-oxoethyl)cycloalkane-1,3-diones 7 and 2-(3-oxopropyl)cycloalkane-1,3-diones 10 also gave the corresponding dioxapropellanes 8 and 11
在乙酸中,在回流温度下,用3-(2-氧乙基)哌啶-2,4-二酮2对1,1-二芳烃1进行基于锰(III)的氧化环化反应,以选择性地生产氮杂二恶英[4.3.3]。螺旋桨3高产。用2-(2-氧乙基)环烷-1,3-二酮7和2-(3-氧丙基)环烷-1,3-二酮10进行类似的环化反应也以中等至良好的产率得到了相应的二氧丙环酮8和11。
