Double Nucleophilic 1,2-Addition of Silylated Dialkyl Phosphites to 4-Phosphono-1-aza-1,3-dienes: Synthesis of γ-Phosphono-α-aminobisphosphonates
摘要:
[Graphics]gamma-Phosphono-alpha-aminobisphosphonates were synthesized from a new class of 4-phosphono-1-aza-1,3-dienes by the addition of dialkyl trimethylsilyl phosphites to these azadienes in the presence of acid. Depending on the steric demand of the group on nitrogen, double 1,2-addition or tandem 1,4-1,2-addition occurred.
