A synthesis of unsymmetrical highly functionalized biaryls with an amino substituent juxtaposed with two nitrile groups in one of the phenyl rings is delineated and illustrated by the carbanion-induced ring-transformation of 6-aryl-4-methylsulfanyl-2H-pyran-2-one-3-carbonitrile (1) and 4-sec-amino-6
