โœฆ Synopsis

A general controlled synthesis of oligoarenes and heteroarenes through base-catalyzed ring transformation of 6-aryl-4-(pyrrolidin-1-yl)-2H-pyran-2-one-3-carbonitriles (1a-d) and methyl 6-aryl-4-methylthio-2H-pyran-2-one-3-carboxylates (1e-h) is described. This procedure offers flexibility in the fabrication of diverse oligoarene ring systems in a controlled fashion.
