| titleOfInvention | Chiral quaternary ammonium salt phase transfer catalyst based on tetramethyl spiroindane skeleton and preparation method thereof |
| abstract | The invention discloses a chiral quaternary ammonium salt phase transfer catalyst based on a tetramethyl spiroindane skeleton and a preparation method thereof. The quaternary ammonium salt compound is a compound with a structure shown in a general formula (I) or an enantiomer, a racemate or a diastereomer of the compound. The novel chiral quaternary ammonium salt compound with the spiro framework, which is developed by the invention, can be used for catalyzing organic reactions, and particularly has excellent catalytic effect when being used as a chiral phase transfer catalyst in glycine Schiff base asymmetric alkylation reactions. |
