| titleOfInvention | Chiral zinc complex |
| abstract | The invention provides a chiral zinc complex. The chiral zinc complex is characterized by being prepared through a reflux reaction of 2-cyanopyridine and L-valinol in a chlorobenzene solvent under anhydrous and anaerobic conditions and a catalyst anhydrous ZnCl2 with a concentration of 65 wt% for 48 hours. The complex has a chemical formula (I) as shown in the specification. The synthetic method for a complex (I) comprises the following steps: subjecting 2-cyanopyridine and L-leucinol to a reflux reaction in the chlorobenzene solvent under anhydrous and anaerobic conditions and the catalyst anhydrous ZnCl2 (65 wt%) for 48 hours, and carrying out separation and purification, i.e., after the reaction is completed, removing chlorobenzene, adding water and carrying out dissolving, then carrying out extraction with chloroform, desolventizing an extraction phase, and carrying out purification through column chromatography; and subjecting a crude product to column chromatography by using petroleum ether/dichloromethane with a volume ratio of 1: 99, and subjecting a first component point to natural volatilization so as to obtain a white crystal complex. The complex provided by the invention shows good catalytic performance in a cyanosilylation reaction, a Henry reaction and a baylis-hillman reaction of benzaldehyde, wherein the conversion rates are 78%, 99% and 66%, respectively. |
