Crystal structure of 5-(4-(1H-tetrazol-5-yl)phenyl)-1H-imidazol-3-ium 7-carboxy-1,3-dioxo-1H,3H-benzo[de]isochromene-6-carboxylate monohydrate 4,5-anhydride, C24H16N6O8 Crystal structure of poly-[diaqua-bis(μ2-2-((1H-1,2,4-triazol-5-yl)thio)acetato-κ2N:O) cadmium(II)]...
(1H-1,2,4-triazol-3-ylcarbamoyl) propanoic acid (HLIII) were synthesized by condensation reaction of 3-amino-1,2,4-triazole (3-AT) with phthalic anhydride, 2,3,4,5-tetrachlorophthalic anhydride and succinic anhydride respectively in refluxing dry methanol, dimethylformamide (DMF) or ethanol...

It was essential to protect the NH2terminal of (S)-alanine2to avoid interference during the coupling reaction. TheN-protection of (S)-alanine3was carried out by the fusion of amino acid with phthalic anhydride [13]. The removal of unreacted phthalic anhydride was easy after the completion of...
