- Method for synthesizing 2-benzamido-3-aryl acrylate
-
The invention discloses a method for preparing 2-benzamido-3-aryl acrylate, and belongs to the field of organic chemical synthesis. The method is mainly implemented by the following steps: adding aromatic aldehyde, ethylhippurate, acetic anhydride and an alkali catalyst into a three-mouth flask according to a certain proportion under the protection of argon, and performing condensation reaction under a certain temperature condition to obtain a 2-benzamido-3-aryl acrylate compound by one step. According to the method, production steps are shortened, the method is easy to operate and control, the production operation environment is improved, the yield and the quality of a product are improved, and the reaction time is shortened; the 2-benzamido-3-aryl acrylate is mainly used for evaluation of the activity of a chiral ligand and catalyst thereof, medicinal synthesis, a pesticide, a photoelectric material and the like.

- Preparation method of chiral alpha-amino acid
-
The invention discloses a preparation method of chiral alpha-amino acid. Initial raw materials comprising aldehyde and N-acryl substituted glycine undergo Erlenmeyer-Plochl cyclization, hydrolysis or alcoholysis, asymmetric catalytic hydrogenation and acid hydrolysis to obtain the chiral alpha-amino acid compound. The method adopting the above synthesis route has the advantages of mild reaction conditions, simple technological operation, safe and stable production, realization of high yield, good chemical purity and good optical purity of the above obtained product, wide application range, and suitableness for industrial production.

- A concise approach to polysubstituted oxazoles from N-acyl-2-bromo enamides via a copper(i)/amino acid-catalyzed intramolecular C-O bond formation
-
A straightforward and efficient copper(i)/amino acid-catalyzed intramolecular Ullmann-type C-O coupling reaction has been developed. This protocol affords a facile methodology for the synthesis of a series of novel 2,4,5-substituted oxazoles from readily accessible N-acyl-2-bromo enamides under mild conditions.
