A series of novel N-anilino-2-substituted-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidine-7-amine derivatives was prepared and evaluated for their in vitro antiprolif
Three chiral stationary phases(CSP1, CSP2 and CSP3)for ligand-exchange chromatography were prepared by firstly using dimethylchlorosilane as an endcapping reage
Thirteen novel sulfonylureas containing thiadiazole moiety were synthesized in a two-step reaction. Their structures were determined using IR, 1H NMR, HRFTMS, a
