A competent method for the synthesis of indolizine-based diarylmethylphosphonates is described. This protocol involves a metal-catalyzed 5-endo-dig-cyclization of 2-(2-enynyl)pyridine derivatives followed by a remote addition of diarylphosphites to provide indolizine-containing diarylmethylphosphonates in good yields.
