  摘要：

  AbstractA ruthenium‐catalysed dehydrogenative cross‐coupling of primary alcohols and imines in the presence of TFA provided a library of differently substituted quinolines. Imines can be prepared in situ from various anilines and several benzyl alcohols using a ruthenium‐catalysed hydrogen‐transfer procedure. Without changing the catalyst, quinolines can be obtained in moderate to good yields by adding various primary alcohols in the presence of TFA (30 mol%) via a “telescopic” protocol. The use of alcohols, the absence of strong oxidants and the diversity of potential starting materials make this modern version of the Skraup reaction superior to most of the conventional quinoline syntheses.magnified image

  A variety of substituted quinolines are synthesized from imines and enolizable carbonyl compounds under aerobic conditions, in which only water is a byproduct. In DMSO, a catalytic amount of HCl activates carbonyl compounds quite effectively to give the quinolines. A simple and practical procedure is demonstrated on a large scale.
