Synthesis of 4-[(2/4-chloro-/2,3-dichloro-/2/4-bromo-/2,4-dinitro-/4-nitrophenyl) anilinemethyl]6-t-butyl-2H-1-benzopyran-2-ones have been carried out. Synthesized compounds were characterized by 1HNMR, IR and other physical and analytical data. All of the synthesized compounds were evaluated for their antifungal activity against Aspergillus awamori and Sclerotium rolfsii and antibacterial acti...
Gas-liquid chromatography-mass spectrometry (GLC-MS) has been used for the separation, detection, and identification of 1,4-benzoxazin-3-ones (hydroxamic acids and lactams) and benzoxazolinones found in maize (Zea mays L.) extracts. Compounds of interest were partitioned into ethyl acetate from aqueous maize seedling extracts. For analysis by GLC-MS, trimethylsilyl derivatives were prepared, ch...
Transformation of 3-propargylmercapto-6 methyl-1, 2,4-triazin- 5 (2H)- one (1; R=CH3) to 3,6- dimethyl-7H- thiazolo [3,2-b] [1, 2, 4] triazin -7- one (2) is performed under basic condition. The formation of (2) may be mainly due to the high reactivity of acetylenes towards nucleophiles and isomerization of the intermediate.
