6-(β-Glycosylamino)purines have been synthesized in good yields by condensation of 4-amino-5-nitro-6-chloropyrimidine with masked glycosylamines followed by hydrogenation of nitro group, cyclization with triethyl orthoformate and removal of protecting groups.

(S)-(+)-Phosphinothricin was prepared in good optical yield by the Michael addition of chiral glycine Schiff base derived from (S)-2-hydroxy-3-pinanone to vinyl phosphorus compound. (R)-(−)-Phosphinothricin, an enantiomeric isomer, can also be prepared from the same chiral glycine Schiff base by choosing suitable reaction temperature.
