A novel pseudo four-component condensation reaction for the efficient synthesis of 2ë5-[1,2]oxaphosphinin compounds using
triphenylphosphine and ethyl bromoacetate in the presence of electron-deficient acetylenic esters without using any catalyst and
activation is reported. Fully functionalized 2ë5-[1,2]oxaphosphinin derivatives can be prepared from simple and readily available
precursors under neutral conditions.
