Using 2,6-(Isopropyl)2-4-Adamantyl-C6H2 substituted BINOL skeleton magnesium phosphate as catalyst, to catalyze the asymmetric reaction of 2-naphthol and tert-Butyl benzylidenecarbamate(Ⅲa). Under the conditions of room temperature, reaction time of 15 h, toluene as solvent, and the amount of catalyst is 5% (based on the amount of substrate material, the same below), the tert-butyl (2-hydroxynaphth-1-yl)(phenyl)methylcarbamate(Ⅳa) produced by the reaction reached 97% yield and 90% enantioselectivity. Characterization using 1HNMR and HPLC. This study optimized the reaction conditions and determined the key parameters such as catalyst, reaction time, solvent, and reaction temperature. A small amount of catalyst can efficiently catalyze the reaction. The reaction condition is mild. And the method is cost-effective and environmentally friendly.
