Novel Method for the Synthesis of α-Amino-α′-hydroxyalkylphosphinic Acids and Bis (α-aminoalkyl) phosphinic Acids: Nuclephilic Addition of α-Hydroxy-H- …
Abstract We report here a novel and simple method for the synthesis of α-amino-α′- hydroxyalkylphosphinic acids in good yields in two simple steps without any protection– deprotection steps. We have developed an efficient method for the synthesis of α-amino-α′- hydroxyalkylphosphinic acids via the reaction of easily available α-hydroxyalkylphosphinic acids with diimines. Treatment of α-hydroxyalkylphosphinic acids with diimines in the ...
