Abstract
1,3-Teraryls 2 were synthesised by reaction of 6-aryl-3-methoxycarbonyl-4-(methylthio)-2H-pyran-2-ones 1 a with aryl methyl ketones. An analogous reaction with 6-aryl-3-cyano-4-(methylthio)-2H-pyran-2-ones 1 b and aryl methyl ketones failed to yield cyano-substituted 1,3-teraryls, but afforded (4,6-diarylpyran-2-ylidene)acetonitriles 4 in poor yields. 6-aryl-3-methoxycarbonyl-4-(methylthio)-2H-pyran-2-one - aryl methyl ketone - carbanion - 1,3-teraryl - ring-transformation reaction
