Economical approach: The first organocatalytic asymmetric intramolecular hydroarylation of phenol‐ and aniline‐derived enals offers one of the most straightforward and atom‐economic approaches to enantioriched chromans and tetrahydroquinolines (up to 96 % ee; see scheme).
经济的方法:苯酚和苯胺衍生的烯类的首次有机催化不对称分子内氢芳基化为对映异构的二价铬和四氢喹啉提供了一种最直接,最经济的方法(ee高达96%;参见方案)。
