A series of novel pyrido[1,2-a]pyrimidine-3-carboxamide derivatives 6a-n were prepared starting from 2(1H) pyridone 1 via hydrolysis, de-carboxylation, selective O-alkylation followed by rearrangement to give pyridine-2-amine 3. Compound 3 on reaction wit

A one-pot transformation of α,β-unsaturated trifluoromethyl ketones with 2-(phenylsulfinyl)acetamide to give trifluoromethylated 2-pyridones is realized. The reaction proceeds under mild conditions and involves multiple steps in an expeditious and controlled sequence to provide efficient access to a broad range of trifluoromethylated 2-pyridones in moderate to high yields. Moreover, further synthetic manipulations permit the routine synthesis of a diverse array of trifluoromethylated pyridines with good efficiency.
