titleOfInvention | Novel method for realizing visible light catalytic asymmetric oxidation by utilizing microreactor |
abstract | The invention belongs to the field of flow chemistry, and provides a novel method for realizing visible light catalytic asymmetric oxidation by using a microreactor. The method utilizes a microreactor to realize continuous preparation of chiral alpha-hydroxy-beta-dicarbonyl compounds by utilizing a cinchona alkaloid derived phase transfer catalyst and catalyzing asymmetric photocatalytic oxidation of beta-dicarbonyl compounds by taking oxygen as an oxidant under the condition of no additional photosensitizer or introduced photosensitive groups under the condition of visible light. The method has the advantages that the reaction temperature is-15-30 ℃, the reaction retention time is 5-200 min, and 100% of substrate conversion rate and enantioselectivity of more than 70% can be realized. The method has the advantages of mild reaction conditions, continuous reaction, catalyst with double-functionalization characteristics of a chiral catalytic center and a photosensitive center, no amplification effect and easy industrialization. |
