Synthesis, Redox Properties and Antibacterial Activity of Hindered Phenols Linked to Heterocycles.

A series of benzotriazole, cyclic amides and pyrimidine derivatives, containing 2,6-di--butyl-phenol fragments, were synthesized. The redox properties of obtained compounds were studied using the cyclic voltammetry on a platinum electrode in acetonitrile. The oxidation potentials of all substances were comparable to those of BHT. The obtained compounds were tested for their antibacterial activity, and -(2-(3,5-di--butyl-4-hydroxyphenyl)-2-oxoethyl)isatin (32 μg/mL) exerted good activity against
