We synthesized 3-O-methylviridicatin 1 and several analogues of this fungal metabolite. We showed that replacement of the methoxy moiety by a thiomethyl enhanced dramatically its ability to inhibit TNF-alpha secretion. These results strongly suggest that 4-phenyl-3-methylthioquinolinone 3 may provide the basis for the development of new anti-inflammatory agents. (c) 2007 Elsevier Ltd. All rights reserved.

The synthesis of aryl-substituted 1,4-dihydroquinolines can be achieved using a [4+2] cycloaddition between benzyne and various aryl-substituted 1-azadienes. The conditions are tolerated by N-aryl-, alkyl-, tosyl-, and tert-butoxycarbonyl-protected 1-azadienes. A short synthesis of the fungal metabolite 3-O-methylviridicatin is reported. benzyne - dihydroquinolines - azadienes - cycloaddition - 3
