AbstractThe synthesis of substituted cage [4.4.2]propellanes and \(D_3}\)-trishomocubanes bearing spiro linkage have been assembled with the aid of Diels–Alder reaction and ring-rearrangement as key steps. Here, readily available 1,4-hydroquinone, isoprene, spiro[2.4]hepta-4,6-diene and spiro[4.4]nona-1,3-diene were used as starting materials. The unusual rearrangement of cage propellanes with zinc/acetic
摘要借助于狄尔斯-阿尔德反应和环重排作为关键步骤,已组装了带有螺环的取代笼型[4.4.2]螺旋桨和\(D_ 3} \)-三气单胞菌的合成。在此,将容易获得的1,4-氢醌,异戊二烯,螺[2.4]庚-4,6-二烯和螺[4.4]壬娜-1,3-二烯用作起始原料。笼状螺旋桨与锌/乙酸的异常重排产生了(D_ 3} \)-三气单胞菌,收率很高。 图形概要通过Diels-Alder反应(DA),[2 + 2]光环加成和酸促进的重排,已经组装了数个笼子[4.4.2]螺旋桨和\(D_ 3} \)-三气单胞菌。在酸催化反应过程中,在笼[4.4.2]丙炔骨架中观察到环重排。重排方法为构建不寻常的多环化合物提供了新的机会。
