Continuing earlier studies designed to obtain compounds of pharmaceutical interest, we used acetyl acetone (1, R=CH3) and ethyl acetoacetate (1, R=OEt) for the preparation of some novel α-amino nitriles (3, 6 and 7). The structures of the new ring systems have been confirmed by IR, NMR and mass spectral data.

Efficient and divergent one-pot synthesis of polyfunctionalized 2-pyridones from β-keto amides based on reaction condition selection was developed. The methodology offers several significant advantages including mild conditions, ease of handling, high yields, and a relatively broad range of substrates. Based on various experiments and observations, a plausible mechanism for the selective synthesis
