Antimicrobial and antiurease activities of newly synthesized morpholine derivatives containing an azole nucleus
(Birkhauser Boston, 2013)
2-[6-(Morpholin-4-yl)pyridin-3-ylamino]acetohydrazide (4) was obtained starting from 6-morpholin-4-ylpyridin-3-amine (2) via the formation of ester (3) and then converted to the corresponding Schiff bases (5, 6) with the ...
Preparation and antimicrobial activity evaluation of some new bi- and triheterocyclic azoles
(Springer Birkhauser, 2013)
Synthesis of the carbothioamides (5, 13, 22) was performed starting from 3H-1,2,4-triazol-3-ones (2, 17) by several steps, and then, these carbothioamides was converted to triheterocyclic compounds incorporating 1,2,4-triazole, ...
