The preparation of gem-diamine derivatives of phosphonates from α-carbamatemethylphosphonates is reported. In our earlier work, the reaction of sulfone with dialkylphosphonate gave α-carbamatemethylphosphonate as the major product. However, gem-diamine derivative of phosphonate was unexpectedly formed as a side product when decreasing the amount of dialkylphosphonate. Although few reports exist on the synthesis of this unique structure, gem-diamine derivatives have shown potential biological activity as an anti-cancer reagent. After optimization, a methodology for the synthesis of gem-diamine derivatives of α-carbamatemethylphosphonate is provided. The reaction of α-carbamatemethylsulfone with α-carbamatemethylphosphonate using LiOH as a base and commercial petroleum ether as solvent provided gem-diamine derivatives in good to excellent yields. This simple protocol runs under very mild conditions, and has a broad substrate scope.

Key words: α-carbamatemethylphosphonate, gem-diamine derivatives, sulfone
