| titleOfInvention | Mono-substituted alkylation compound preparation method |
| abstract | The invention relates to a mono-substituted alkylation compound preparation method, and specifically provides a method for preparing an alpha-amino acid asymmetric mono-substituted alkylation compound represented by the specific formula by using aldimine type Schiff base. According to the method of the present invention, in a media, in the presence of an optically-active quaternary ammonium salt phase transfer catalyst and an inorganic base, an aldimine type Schiff base alkylation step is started to be performed and quenching is performed before completing the stoichiometric reaction of the alkylation reaction so as to obtain the high optical-purity mono-substituted alkylation compound. |
