Enantioselective synthesis of potentially useful chiral 3-aryl-1-indanones was achieved through a rhodium-catalyzed asymmetric intramolecular 1,4-addition of pinacolborane chalcone derivatives using extraordinary simple MonoPhos as chiral ligand under relatively mild conditions. This novel protocol offers an easy access to a wide variety of enantioenriched 3-aryl-1-indanone derivatives in high yields
对映选择性合成潜在有用的手性3-芳基-1-茚满酮是通过在相对温和的条件下,使用非常简单的MonoPhos作为手性配体,通过铑催化的频哪醇硼烷查尔酮衍生物的不对称分子内1,4-加成而实现的。这种新颖的方案可轻松获得高收率(最高95%)且对映选择性(最高ee达95%)的多种对映体富集的3-芳基-1-茚满酮衍生物。
