Synthesis of 3-acetyl-4-hydroxy-1-phenylpyridin-2(1H)-one derivatives

The cyclization of aryl ketone anilides 3 with diethyl malonate to affords 4-hydroxy-6-phenyl-6H-pyrano [3,2-c]-pyridin-2,5-diones 4 in good yields. 3-Acetyl-4-hydroxy-1-phenylpyridin-2(1H)-ones 5 are obtained by ring-opening reaction of 4-hydroxy-6-pheny

Thermal Cyclization of 3-Acyl-4-azidopyridines to Isoxazolo[4,3-c]pyridines

4-Azidopyridines such as 3-acetyl-4-azido-2-pyridones 3 or 4-azido-3-ethoxycarbonylpyridine 7 with reactive ortho-acyl substituents were obtained from the 4-hydroxy-2-pyridones 1, resp. 5 via 4-tosyloxy-2-pyridones 2 or the 2,4-dichloropyridine 6. DSC-ass
