- W4377824857 abstract "Abstract NaN 3 -catalysed three-component reaction between trialkyl phosphites, dialkyl acetylenedicarboxylates and ethyl arylmethylidenecyanoacetates afforded phosphonated cyclopentenone derivatives. The process involves one C-P and two C-C bond formations in one synthetic step. All reactions were conducted in acetone as solvent at room temperature and the products were obtained in high yields as stable solids. The products were isolated and purified by simple washing with water and diethyl ether without need to tedious chromatography methods. The structures of products were proved by 1 H, 13 C and 31 P NMR and IR spectral and elemental analysis data." @default.
