1496 results about "Isoquinoline" patented technology

Isoquinoline is a heterocyclic aromatic organic compound. It is a structural isomer of quinoline. Isoquinoline and quinoline are benzopyridines, which are composed of a benzene ring fused to a pyridine ring. In a broader sense, the term isoquinoline is used to make reference to isoquinoline derivatives. 1-Benzylisoquinoline is the structural backbone in naturally occurring alkaloids including papaverine. The isoquinoline ring in these natural compound derives from the aromatic amino acid tyrosine.

Synthetic method and application of covalent organic framework (COF) material

The invention discloses a synthetic method of a covalent organic framework (COF) material. The method comprises the following steps: after mixing 1,3,5-benzenetricarboxaldehyde with 2,5-di(N,N-dimethyl)amino-1,4-benzdihydrazide uniformly in an organic solvent, reacting in the presence of a catalyst acetic acid to obtain the COF material, wherein the mole ratio of 1,3,5-benzenetricarboxaldehyde to 2,5-di(N,N-dimethyl)amino-1,4-benzdihydrazide is 1:(0.5-3). The COF material obtained by adopting the method has relatively large specific surface area and regular open framework structure with adjustable diameter, thus being beneficial for mass transfer of reactants and products in photoabsorption and catalytic processes; the material can serve as a photocatalyst and can increase the yield of the dehydrogenative coupling reaction between 2-phenyl-1,2,3,4-tetrahydroisoquinoline and nitromethane from 39% in the absence of catalysts to 89%.
