The purpose of this work was to determine the tautomerism, the conformational analysis and photoreactivity of dehydroacetic acid (DHAA, 1). For that reason, the photolysis of DHAA (1) was performed at 254 nm and compared with two structurally similar

Soybean residues were transformed through static pyrolysis carried out at temperatures between 250 °C and 350 °C. The gaseous fraction analysis showed that the gases emanated in the pyrolysis are mainly CO2 and CO. Furthermore, it was proved that t

The growing interest in the chemistry of unsaturated ring-fused 1,3-heterocycles, in this particular case 1,3-oxazines, arise in part from their versatile pharmacological applications. In the present article, the evaluation of the in vitro and ex viv
