A new enantioselective approach to obtain a tetrasubstituted chiral center at the C3 position of oxindoles via a catalytic asymmetric Morita–Baylis–Hillman reaction has been demonstrated. This reaction provides 3‐substituted 3‐hydroxy‐2‐oxindoles in good to excellent yields and ee values, which could be facilely transformed to pharmaceutically more interesting compounds.
已经证明了一种新的对映选择性方法,该方法通过催化不对称Morita-Baylis-Hillman反应获得在羟吲哚C3位置的四取代手性中心。该反应可提供3-取代的3-羟基-2-氧吲哚,其收率和ee值都非常好,并且可以很容易地转化为药学上更有趣的化合物。
