A novel three-component stereoselective synthesis of (E)-4-alkene 1,3-diketones from lithium selenolates, 1-(1-alkynyl)cyclopropyl ketones, and aldehydes is reported. This reaction afforded the products in moderate to good yields with the formation of a new C–Se single bond, a new C–C double bond, and a new C–O double bond.
报道了由亚硒酸锂,1-(1-炔基)环丙基酮和醛类新型新颖的三组分立体选择性合成(E)-4-烯烃1,3-二酮的方法。通过形成新的C-Se单键,新的C-C双键和新的C-O双键,该反应使产物收率处于中等至良好的水平。
