Abstract:
Objectives. With the growing resistance of pathogenic microorganisms to antibiotics, the development of new antimicrobial drugs offering specific mechanisms of action becomes an urgent task. Only few antimicrobials offer a broad spectrum of activity against gram-positive and gram-negative bacteria, molds, and yeasts. In this regard, the purpose of the work was to develop methods for synthesizing biologically active derivatives of alkyl-substituted phenols (reactions at the hydroxy group) to study their biological effect.Methods. The synthesis of imidazole acetates of substituted phenols was ca

Abstract:
Thiazolopyrimidnes are considered one of the most interesting classes in heterocyclic chemistry due to their pharmaceutical importance. Herein, we report the synthesis of some new heterocyclic compounds containing thiazolopyrimidine starting from compound (1) which was previously prepared in literature. The starting compound was allowed to react with different alkylating agents such as chloroacetone, chloroacetyl chloride, and phenacyl bromide to afford derivatives (2-4). Compound (5), benzylidene derivative, was obtained by the reaction of compound (2) with benzaldehyde while amino-dicarbonit
