Facile four-component domino reactions for the synthesis of highly functionalized tetrahydroquinolones
摘要:
The four-component domino reactions of (E)-3-(dimethylamino)-1-arylprop-2-en-1-ones with anilines, aromatic aldehydes, and 1,3-cyclohexanediones in an equimolar ratio in acetic acid afforded functionalized tetrahydroquinolones in good yields. This one-pot transformation involves the formation of two C-C and two C-N bonds in a single synthetic operation. (C) 2013 Elsevier Ltd. All rights reserved.
