In conclusion, we have reported herein that dialkyl
phosphites are powerful reagents for radical translocation/
cyclization reactions that start from readily available terminal
alkynes. A simple one-pot procedure has been developed.
The excess reagent is easily removed by evaporation, and
filtration through a short pad of silica gel affords a clean
reaction product. The cyclic phosphonates produced by this
reaction cascade are particularly attractive for further transformations.[

of natural products is currently underway.
