摘要

Abstract

A new phosphaneoflavonoid was obtained by the reaction oxaphosphinine with β-resorcylic acid. A method was proposed for the synthesis of new unsymmetrical cage phosphonates based on 4-aryl-2-hydroxy-5,7,8-trimethylbenzo[e][1,2]oxaphosphinine-2-oxides as a result of intramolecular heterocyclization. Composition and structure of all the obtained compounds were confirmed by ¹H, ¹³С and ³¹P NMR, IR spectroscopy and mass spectrometry data.
