Abstract
Substituted (8-aminobenzyl)dinaphthodioxaphosphocine 8-oxides were prepared in a two-step process. The first step of the reaction is one-pot synthesis of α-aminophosphonates by the reaction of aldehydes, amines, and trialkyl phosphite in the presence of ceric ammonium nitrate. The second step is cyclization of α-aminophosphonates with bis(2-hydroxy-1-naphthyl)methane in the presence of a catalytic amount of p toluenesulphonic acid under reflux conditions. Their structures were established by elemental analyses, IR, 1H, 13C, 31P NMR, and mass spectral data.
