DIBENZYL DIETHYLPHOSPHORAMIDITE Chemical Properties,Usage,Production

Chemical Properties

Clear Colourless Liquid

Uses

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

Uses

Dibenzyl diethylphosphoramidite is a useful reagent for the efficient phosphorylative conversion of alcohols into their corresponding dibenzylphosphorotriesters as well as dibenzyl glycosyl phosphites, which can easily be converted to glycosyl phosphates or used in glycosylation reagents in oligosaccharide synthesis.

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.
