An efficient method for the synthesis of homopropargylboronates by copper‐catalyzed alkynylboration of alkenes with diboron reagents and bromoalkynes has been developed. The alkynylboration reaction features high selectivity and efficiency, mild reaction conditions, wide substrate scope, and functional‐group compatibility, and is a highly attractive complement to existing methods for the synthesis
已开发出一种有效的方法,该方法通过铜与二硼试剂和溴炔烃的铜催化的炔基硼烷基化反应合成高炔丙基硼酸酯。炔基硼酸酯化反应具有高选择性和高效率,温和的反应条件,广泛的底物范围和官能团相容性,是现有合成高炔丙基硼酸酯方法的极富吸引力的补充。硼基和炔基基团都是用于后续操作的良好的潜在官能团,其提供了进入各种重要分子结构的途径。
