A two-stage synthesis of 5-aroyl-2-aryl-3-hydroxypyridin-4(1H)-ones (56–66% overall yields) was carried out by refluxing 5-aroyl-3-(benzyloxy)-2-(het)aryl-4H-pyran-4-ones with ammonium acetate in AcOH and subsequent debenzylation. The prepared N-un

This work describes the synthesis of 3-hydroxy-3,4-dihydropyrido[2,1-c][1,4]oxazine-1,8-diones, their tautomerism, and reactivity towards binucleophiles. These molecules are novel and convenient building-blocks for the direct construction of biologic

A straightforward approach for the construction of the new class of conjugated pyrans based on enamination of 2-methyl-4-pyrones with DMF-DMA was developed. 2-(2-(Dimethylamino)vinyl)-4-pyrones are highly reactive substrates that undergo 1,6-conjugat

Dehydroacetic acid and triacetic acid lactone are known to be versatile substrates for the synthesis of a variety of azaheterocycles. However, their fluorinated analogs were poorly described in the literature. In the present work, we have investigate
