| titleOfInvention | A kind of preparation method of chirality azetidinones |
| abstract | The preparation method of a kind of chirality azetidinones, reacts the chiral reduction agent BINAL H of Formula II with 1～10 times of mol ratio 2～10 hours at 20 DEG C～30 DEG C, obtains the Formulas I of single configuration.This method only needs a kind of reducing agent, and cost is relatively low；Product quality is good, and optical purity and chemical purity all can reach more than 95%, are suitable to industrialized production. |
