A new class of pyrimidinylsulfamoyl azolyl acetamides was prepared from 2-pyrimidinylsulfamoyl acetic acid and 2-aminoazoles. The methoxy substituted pyrimidinylsulfamoyl oxazolyl acetamide (8e) displayed moderate antioxidant activity. The methyl and methoxy substituted pyrimidinylsulfamoyl oxazolyl acetamides (8b, 8e) exhibited antiviral activity on BHK 21 cell lines with IC50 63.5, 44.5 µg/mL, respectively
the presence of dispersed sodium in THF under ultrasonication is reported. The corresponding heteroaryl sulfonamido esters are directly condensed with heteroaryl amines to get amido sulfonamido heteroaromatics in the presence of a mild base in THF under ultrasonication. Utilization of easy reaction conditions, shorter reaction times, and isolation of products in high yields under ultrasonication make

(1) The benzoxazolyl/benzothiazolyl/benzimidazolyl pyrimidines were prepared under ultrasonication in the presence of pyridine/dimethylaminopyridine and triethylamine. (2) Better yields were recorded in 4‐(N,N‐dimethylamino)pyridine and Et3N. (3) The presence of electron withdrawing chloro, bromo, and nitro substituents enhanced antimicrobial activity (13c, 13e, 14e: minimum inhibitory concentration = 6

Herein we report an iron‐catalyzed multicomponent dehydrogenative functionalization of alcohols to pyrimidines under atmospheric conditions. Using a well‐defined Fe(II)‐complex featuring redox noninnocent 2‐phenylazo‐(1,10‐phenanthroline) ligand, as a catalyst, a wide array of 2,4,6‐trisubstituted pyrimidines were prepared via dehydrogenative coupling of primary and secondary alcohols with amidines

Some new 2-iminothiazolidin-4-ones having pyrimidine ring have been synthesized by reaction of substitutedN-(per-O-acetyl-β-D-glucopyranosyl)-Nʼ-(4ʼ,6ʼ-diarylpyrimidine-2ʼ-yl)thioureas with ethyl bromoacetate. The structure of isomeric products has been confirmed by spectroscopic methods, such as IR,1H and13C NMR.
