Abstract:
     The preparation method involves using (minus or plus)-1,1'-bi-2-naphthol, boride, and photoactivated amine to obtain two diastereomeric isomerides of 1,1'-bi-2-naphtholamine borate derivate, then treating them through acidifying, hydrolysis and fine purification respectively. The optical purity of these two antimers is not less than 99
Time: 9
