| N-BENZYLCINCHONINIUM CHLORIDE Usage And Synthesis |
| Chemical Properties | Solid | | Uses | Phase-transfer catalyst involved in:- Enantioselective alkylation of malonic diester with alkyl halides
- Hydrolysis of enol esters
- Asymmetric 6π electrocyclization for synthesis of functionalized indolines
- Asymmetric Michael addition
- Alkylation of monosubstituted indolinones with alkylhalides
- Asymmetric destruction and kinetic resolution of 1-benzylated Reissert compounds
| | Purification Methods | Recrystallise the chloride from isoPrOH, toluene or small volumes of H2O. It is a good chiral phase transfer catalyst [Julia et al. J Chem Soc, Perkin Trans 1 574 1981, Hughes et al. J Am Chem Soc 106 446 1984, Hughes et al. J Org Chem 52 4745 1987]. |
