the synthesis of α,β-alkynyl ketones from nitriles and alkynyldimethylaluminum reagents, derived from trimethylaluminum and alkynes, is described. This methodology provides access to a wide range of α,β-alkynyl ketones with aliphatic, aromatic, and heteroaromatic substituents in moderate to high yield (53–90%). In the cases of aryl-substituted nitriles, the product can also be obtained as α,β-alkynyl
描述了一种从腈类和炔基二甲基铝试剂合成 α,β-炔基酮的简单有效方法,该试剂源自三甲基铝和炔烃。该方法提供了以中等至高产率 (53–90%) 获得各种具有脂肪族、芳香族和杂芳香族取代基的 α,β-炔基酮的途径。在芳基取代腈的情况下,也可以高产率 (88-93%) 以 α,β-炔基 NH 酮亚胺的形式获得产物。
