| titleOfInvention | A kind of chiral oxazoline crystal compound and its application |
| abstract | A kind of chiral oxazoline crystal compound, its chemical formula is as follows: , the chiral oxazoline crystal compound was synthesized in a 100mL two-neck flask under anhydrous and oxygen-free conditions, adding anhydrous ZnCl 2 ? 5.0g, 40ml of chlorobenzene, 5.0g (32.0mmol) of o-diacetonitrile benzene, 15.6g of chiral L-valinol, the mixture was refluxed at high temperature for 72h, the reaction was stopped, the solvent was removed under reduced pressure, and the residue was dissolved in water Dissolve and extract with CHCl 3 (20mLx2), dry the organic phase with anhydrous sodium sulfate, spin to remove the solvent, and use petroleum ether/dichloromethane (1:1) column chromatography to obtain a blue oily liquid (II) , recrystallized with a mixed solvent of petroleum ether, chloroform and ethanol to obtain blue crystal (I); as a catalyst, it showed good catalytic activity in the Henry reaction of benzaldehyde. |
