A facile one pot synthetic path for the preparation of pyrimidine-5-carbaldehydes from alpha-formylaroylketene dithioacetals is described. Amidines were allowed to react with alpha-formylaroylketene dithioacetals in DMF or acetonitrile to afford the pyrimidine-5-carbaldehydes. The starting compounds reported earlier were synthesized from alpha-oxoketene dithioacetals in excellent amount. (C) 2007 Elsevier Ltd. All rights reserved.
