General description

Dibenzyl N,N-diethylphosphoramidite is repoted to be suitable reagent for the efficient 1H-tetrazole-catalyzed ′phosphite-triester′ phosphorylation of the protected serine derivatives.

Application

Dibenzyl N,N-diethylphosphoramidite may be used:
  • as phosphitylating reagent in the synthesis of glycosyl phosphites and phosphates
  • for phosphorylating the alcohols
  • in the preparation of 6-dibenzylphosphate-1,3,5-tri-O-PMB-myo-inositol
