Synthesis, characterization, and antimicrobial activity of some new phosphorus macrocyclic compounds containing pyrazole rings

Abstract

A simple synthetic method is reported for the preparation of some new phosphorus macrocycles in which the pyrazole rings are appended to a phosphorus atom. The methodology is based on the cyclocondensation reaction of bis(4-formylpyrazolyl) phosphine oxides (1a, 1b) with nitrogen nucleophiles that contain active terminal amino groups. The antimicrobial activities of the synthesized compounds were assayed. © TÜBITAK.
