Reduction, please! The title reaction affords α‐hydroxyketones, a common structural motif in biologically active natural products, in good yields and high enantioselectivities at room temperature. The commercially available ansa‐titanocene 1 was found to be an efficient catalyst for this process, which presumably proceeds by addition of a ketyl radical to a nitrile.
请减少!标题反应可在室温下以高收率和高对映选择性提供α-羟基酮,这是生物活性天然产物中常见的结构基序。人们发现市售的ansa-titanocene 1是该过程的有效催化剂,据推测可通过向腈中添加酮基来进行。
