A highly stereo- and regiocontrolled reaction between allenamides, alkynes, and a bis-metallative reagent (Me2PhSiBpin and Et3SiBpin) is reported for the first time. This new method for accessing functionalized 1,4-dienes under phosphine-free palladium catalysis has good functional group compatibility as showcased through late-stage diversification. By virtue of computational calculations and experimental
首次报道了丙二酰胺、炔烃和双金属试剂(Me 2 PhSiBpin 和 Et 3 SiBpin)之间的高度立体和区域控制反应。这种在无膦钯催化下获得功能化 1,4-二烯的新方法具有良好的官能团兼容性,如后期多样化所示。凭借计算计算和实验证据,证实了区域和立体化学洞察力。
