  Synthesis of [5,6]-fused pyridocoumarins through aza-Claisen rearrangement of 6-propargylaminocoumarins

  摘要：

  [5,6]-Fused pyridocoumarins are prepared through aza-Claisen rearrangement and subsequent in situ cyclization of 6-propargylaminocoumarins under microwave irradiation in the presence of boron trifluoride diethyl etherate in N,N-dimethylformamide. During this process demethoxycarbonylation is observed in the corresponding 4-carbomethoxycoumarin derivatives. (C) 2011 Elsevier Ltd. All rights reserved.

  pyridocoumarins are prepared from the Povarov-type, three-component reactions of 6- or 7-aminocoumarins with n-butyl vinyl ether, catalyzed by iodine in refluxing acetonitrile, through the aza-Diels–Alder reaction of the initially formed N-iminoaminocoumarins with a second equivalent of the vinyl ether.

  2,4‐Diphenyl substituted fused pyridocoumarins have been synthesized by one‐pot three‐component domino reactions of aminocoumarins, benzaldehyde, and phenylacetylene by using FeCl3 (10%) as catalyst under reflux or MW irradiation. The new compounds were tested as inhibitors of lipid peroxidation. The 7,9‐diphenyl‐2H‐pyrano[2,3‐g]quinolin‐2‐one presents interesting results and could serve as lead compound
