diorganocuprates to ⇌,β-unsaturated ketones and regiospecific trapping of the resulting enolate with ⇌-trimethylsilyl vinyl ketones is presented. The stereochemical details of the process have been elucidated and are discussed. Application of this methodology to the synthesis of a variety of polycyclic ketone structures is described including applications to steroid synthesis.
提出了一种新的环化方法,该方法基于在⇌,β-不饱和酮中添加双有机铜酸酯,并用⇌-三甲基甲硅烷基乙烯基酮对所得烯醇化物进行区域特异性捕集。已经阐明并讨论了该方法的立体化学细节。描述了该方法在多种多环酮结构的合成中的应用,包括在类固醇合成中的应用。
