α-Iodo-α,β-unsaturated ketones such as compound 1 serve as vicinal dielectrophiles and react with a range of dinucleophiles including pentane-2,4-dione and 1,3-indandione to produce [3 + 2]- and [2 + 1]-adducts such as 5 and 38, respectively. [4 + 2]- and [5 + 2]-cycloadducts have been obtained from compound 1 by related means. Preliminary studies reveal that α-iodinated α,β-unsaturated esters can
α-Iodo-α,β-不饱和酮,例如化合物1,可作为连位介电试剂,与一系列双亲核试剂(包括戊烷-2,4-二酮和 1,3-茚二酮)反应生成 [3 + 2]- 和 [2 + 1]-加合物,例如5和38,分别。[4 + 2]-和[5 + 2]-环加合物已通过相关方法从化合物1中获得。初步研究表明,α-碘化 α,β-不饱和酯也可以参与其中至少一些相同的过程。
