摘要：

2-Ethyl-3-phenacyl-4,5-dihydrooxazolium bromide 1 enolizes spontaneously in dimethyl sulfoxide solution. Condensation with phosphorus trichloride nevertheless involves both the methylene groups in 2- and 3-position and thus yields a five-membered ring. Hydrolysis of the resulting 1-methyl-3-benzoyl-5,6-dihydro-1,3-azaphospholo[5,1-b]oxazole 2 selectively opens the P-C3 bond of the azaphosphole ring to give the zwitterionic 4,5-dihydrooxazolio phosphinate 3.
