Mannich-type reactions of α-amido p-tolylsulfones with diethyl fluoromalonates and diethylmalonates, respectively in presence of catalytic amount of DBU have been developed. A variety of α-amido p-tolylsulfones prepared from aromatic and aliphatic aldehydes reacts with diethyl fluoromalonates and diethylmalonates, respectively under mild reaction conditions to afford α-fluoro β-amino esters and β-amino
