SYNTHESIS AND ITS STEREOCHEMISTRY OF AMINOPHOSPHONIC ACIDS DERIVED FROM 5-HYDROXYMETHYLFURFURAL

Abstract Some dialkyl N-substituted-α-amino-α-furylmethanephosphonates were synthesized via the addition of dialkyl phosphites to corresponding imines in mild conditions in a short time. When an imine is chirally N-substituted the reaction is stereoselective. Stereochemical aspects of the reaction in the light of Cram rules is discussed in this paper.
