title: The green approaches for the synthesis of N-dehydroabietic alpha-aminophosphonates.
abstract: Three kinds of O,O-diethyl N-dehydroabietic aminoarylmethylphosphonates were synthesized from natural product derivatives by two steps of solvent-free reactions through imines intermediates and their structures were characterized by IR, (1)H NMR and (31)P NMR spectroscopy. The solvent-free reactions afforded good yields of N-dehydroabietic imines and alpha-aminophosphonates although the strong space block of dehydroabietylamine to amino group. The green approaches resulted negligible waste and the reactions were environment friendly without using noxious solvents.
