Visible-light-mediated tandem phosphorylation/cyclization for the synthesis of phosphorylated oxindoles.

The visible-light-mediated tandem phosphorylation/cyclization of N -arylacrylamides with H-phosphine oxides has been developed for the synthesis of phosphorylated oxindoles. This efficient and facile process was useful for the construction of a C-P bond and triggered the formation of a C-C bond with good compatibility with functional groups undermild reaction conditions.
