| titleOfInvention | Preparation of optically active diol |
| abstract | PURPOSE: To complete a reaction in a short time only by stirring, to eliminate purification process, and to obtain the titled compound in high optical purity in high yield, by using an optically active 1,2-diphenylethylamine complex as a catalyst, dimerizing a phenol. n CONSTITUTION: Any enantiomer of 1,2-diphenylethylamine, an easily obtainable optically active amine, in an excess amount based on a phenol, is processed into a copper complex, the phenol such as 9-pydroxyphenanthrene, etc. is added to the complex, reacted at -80W100°C, the reaction product is purified by column chromatography, to obtain the desired compound such as (S)-(-)-2,2'-dihydroxy-1, 1'-biphenanthryl, etc. shown by the formula (R 1 WR 4 are H, alkyl, alkoxy, halogen, alkenyl, any neighboring two may form aromatic ring). n EFFECT: A catalyst used can be quantitatively recovered as a hydrochloride, regenerated and reused by treating it with NaOH. n COPYRIGHT: (C)1985,JPO&Japio |
