The present article describes the synthesis of new 10H-phenothiazines using the Smiles rearrangement. These synthesized phenothiazines on oxidation with 30% hydrogen peroxide in glacial acetic acid yield sulfones, and when treated with sugar give ribofuranosides. These compounds are evaluated for their anthelmintic and antimicrobial activities. The structural assignment of the synthesized compounds is made on the basis of elemental analysis and spectroscopic data.
A series of novel fluorinated 10H-phenothiazines were synthesized via Smiles rearrangement. 10H-phenothiazines on refluxing with 30% hydrogen peroxide in glacial acetic acid gave 10H-phenothiazines-5, 5-dioxides (sulphones). These synthesized 10H-phenothiazines were then used as base to prepare ribofuranosides by treating them with sugar (β-D-ribofuranosyl-1-acetate-2, 3, 5-tribenzoate). The synthesized compounds were screened for antimicrobial activity and anthelmintic activity. The structural assignments of compounds were made on the basis of spectroscopic data and elemental analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
