A copper-catalyzed three-component carboboration of acetylene with BPin and Michael acceptors is reported. In this reaction, a cheap and abundant C2 chemical feedstock, acetylene, was used as a starting material to afford -alkenyl boronates bearing a homoallylic carbonyl group. The reaction was robust and could be reliably performed on the molar scale. Furthermore, the resulting -alkenyl boronates could be converted to diverse functionalized molecules with ease.
报道了一种铜催化的乙炔与频哪醇硼烷（BPin）和迈克尔受体的三组分碳硼化反应。在该反应中，一种廉价且丰富的C2化学原料乙炔被用作起始原料，以得到带有高烯丙基羰基的β-烯基硼酸酯。该反应性能良好，能够在摩尔规模上可靠地进行。此外，所得的β-烯基硼酸酯可以轻松地转化为各种功能化分子。
