L. Cottier et al., SYNTHESIS AND ITS STEREOCHEMISTRY OF AMINOPHOSPHONIC ACIDS DERIVED FROM 5-HYDROXYMETHYLFURFURAL, Phosphorus, sulfur and silicon and the related elements, 116, 1996, pp. 93-100
Some dialkyl tituted-alpha-amino-alpha-furylmethanephosphonates were s
ynthesized via the addition of dialkyl phosphites to corresponding imi
nes in mild conditions in a short time. When an imine is chirally N-su
bstituted the reaction is stereoselective. Stereochemical aspects of t
he reaction in the light of Cram rules is discussed in this paper.
