Generation of Oxyphosphonium Ions by Photoredox/Cobaloxime Catalysis for Scalable Amide and Peptide Synthesis in Batch and Continuous-Flow

Phosphine-mediated deoxygenative nucleophilic substitutions, such as the Mitsunobu reaction, are of great importance in organic synthesis. However, the conventional protocols require stoichiometric oxidants to trigger the formation of the oxyphosphonium i

Manganese Catalyzed Direct Amidation of Esters with Amines

The transition metal catalyzed amide bond forming reaction of esters with amines has been developed as an advanced approach for overcoming the shortcomings of traditional methods. The broad scope of substrates in transition metal catalyzed amidations remains a challenge. Here, a manganese(I)-catalyzed method for the direct synthesis of amides from a various number of esters and amines is reported with unprecedented substrate scope using a low catalyst loading. A wide range of aromatic, aliphatic, and heterocyclic esters, even in fatty acid esters, reacted with a diverse range of primary aryl amines, primary alkyl amines, and secondary alkyl amines to form amides. It is noteworthy that this approach provides the first example of the transition metal catalyzed amide bond forming reaction from fatty acid esters and amines. The acid-base mechanism for the manganese(I)-catalyzed direct amidation of esters with amines was elucidated by DFT calculations.

Preparation method of itopride hydrochloride

The invention relates to a preparation method of itopride hydrochloride and belongs to the technical field of raw material preparation. The technical scheme is as follows: the preparation method of itopride hydrochloride comprises the steps as follows: an intermediate I is prepared from initial materials including 3,4-dimethoxybenzamide, formaldehyde and phenol with a one-pot method; the intermediate I and N,N-dimethyl chloroethane hydrochloride are subjected to a substitution reaction to produce an intermediate II; finally, itopride hydrochloride is prepared through salification. The itopridepreparation process comprises a short and convenient route and is economical and environmentally friendly.
