Chemistry of novel compounds with a multifunctional carbon structure. 5. Molecular design of versatile building blocks for aliphatic monofluoro molecules by manipulation of multifunctional carbon structure
A simple and novel method to the synthesis of 3-fluoro-4-aryl-2-pyridone from a Michael-adduct of fluoronitroacetate and alpha,beta-unsaturated ketone is reported. With (NH4)(2)CO3 as the N-source and TsOH as the promoted acid, a series of fluorinated-pyridones was obtained with moderate to good yields. Crown Copyright (C) 2011 Published by Elsevier Ltd.
