1, 1’-bi-2-naphthol 환상의 인산에스테르 化合物을 利用한 아미노알코올의 光學分割

Optical resolution of Aminoalcohol with Active Cyclic 1,1’-bi-2-naphthol Phosphoric Acid

Optical resolution of aminoalcohols had been achived efficiently by use of (R)-2,2’-dihydroxy-1,1’-binaphtholphosphoric acid as the resolving agent in various organic solvents. Racemic aminoalcohols were resolved very easily and high enantiomer yield (about 70% e,e) in THF. On the other hand, absolute configuration of resolved aminoalcohol was (R)-configuration but one of the Valinnol and Phhenylglycinol was anti-type because of sterichindrance.Optical resolution of aminoalcohols had been achived efficiently by use of (R)-2,2’-dihydroxy-1,1’-binaphtholphosphoric acid as the resolving agent in various organic solvents.
