to the synthesis of 2-hydroxyaryl-alkenylphosphine oxides and dialkyl (diaryl)-(2-methyl-4-oxopent-2-yl)phosphine oxides was developed that involves an interaction of Grignard reagents with available benzo[e]-1,2-oxaphosphorinines and 1,2-oxaphospholene-2-oxide. This approach allows obtaining target compounds with a high yield. The synthesized phosphine oxides proved to be highly efficient extractants

Here we report the synthesis, in vitro antimicrobial activity, preliminary toxicity and mechanism study of a new series of 2-(2-hydroxyaryl)alkenylphosphonium salts with the variation of phosphonium moiety obtained by a two-step synthetic method from phosphine oxides. The salts showed pronounced activity against Gram-positive bacteria, including MRSA strains, and some fungi. Mechanism of action against

A new two-step synthesis of phosphonium salts from phosphine oxides using Grignard reagents is reported. This approach involves a cyclization of Z-dialkyl-(diaryl)[2-(5-chloro-2-hydroxyphenyl)-2-phenylvinyl]phosphine oxides under the action of sulfinyl chloride with the formation of 2,2-dialkyl(diaryl)-6-chloro-4-phenyl-2H-1,2-benzoxaphosphinin-2-ium chlorides followed by ring opening under the action
报道了使用格氏试剂由氧化膦新的两步合成phospho盐的方法。该方法涉及在亚磺酰氯的作用下将Z-二烷基-(二芳基)[2-(5-氯-2-羟基苯基)-2-苯基乙烯基]膦氧化物环化,形成2,2-二烷基(二芳基) -6-氯-4-苯基-2 H -1,2-苯并氧杂膦-2-氯化物,然后在有机镁化合物的作用下开环。该方法成功地用于制备一系列带有在磷原子上具有广泛取代基的酚部分的新型phospho盐。合成的salts盐具有很高的体外抗菌和抗真菌活性,并且对人的红细胞毒性低。
