Abstract A facile procedure for the solid‐phasesynthesis of cycloalkylphosphonates and 1‐cycloalkenylphosphonates in good yields and high purities using polystyrene‐supported phenylsulfonylmethylphosphonates with traceless sulfone linker strategy is described.
Cycloalkylphosphonates 5 with ring size varying from 4 to 6 were synthesized in good overall yields, in two steps from trichloromethylphosphonates and Ï-dibromoalkanes, via the corresponding α-trimethylsilyl cycloalkylphosphonates 4.
