A highly regio- and stereoselective synthesis of stereodefined β,β-disubstituted alkenyl ethers featuring the sequential hydroboration/Suzuki–Miyaura coupling of ynol ethers has been described. A number of functional groups, including OMe, Ac, CO2Et, CN, halides, and alkyl, (hetero)aryl, and alkenyl groups, are well-tolerated under the reaction conditions. Furthermore, it allows a facile entry to the
已经描述了具有顺式硼氢化/铃木-宫浦偶联的炔醇醚的立体定义的β,β-二取代烯基醚的高度区域选择性和立体选择性合成。在反应条件下,包括OMe,Ac,CO 2 Et,CN,卤化物和烷基,(杂)芳基和烯基在内的许多官能团具有良好的耐受性。此外,它允许通过TFA介导的β,β-二取代乙烯基醚的水解容易地进入不稳定的二芳基乙醛。
