P -TsOH-promoted synthesis of (E)-6-phenyl-7-styryl-5,6-dihydrodibenzo [b, h] [1,6]naphthyridines via cascade intramolecular aza-Michael addition/Friedlander condensation of 2′-aminochalcones in a SDS/H2O system

Br?nsted acid-promoted cascade synthesis of novel (E)-6-phenyl-7-styryl-5,6-dihydrodibenzo[b,h][1,6]naphthyridines has been achieved via homodimerization of 2′-aminochalcones by employing sodium dodecylsulphate (SDS) as a surfactant in water. Besides water as an environmentally benign reaction medium, the reaction proceeds smoothly with high atom-economy under a sequential one-pot protocol.

Paragraph 0071; 0072; 0073; 0074; 0075; 0076, (2018/10/19)
The invention relates to the field of medicine technology, and a series of novel 2-aryl-2,3-dihydrogen-4(1H)-quinolinone semicarbazone derivatives (I) and pharmaceutically acceptable salts, solvates,optical isomers or polymorphs are designed and synthesized. The derivative (I) and its pharmaceutically acceptable salt, solvate, optical isomer or polymorph can be mixed as an active ingredient witha pharmaceutically acceptable carrier to prepare a pharmaceutical composition. A double dilution method is used for test of the antifungal activity of the derivative (I) and its pharmaceutically acceptable salt, solvate, optical isomer or polymorph, and the results show that the derivative has stronger killing effect on clinically common pathogenic fungi, and is expected to overcome the defects oflarge toxic and side effects, easy generation of drug resistance of azole antifungal medicines which are widely used clinically. The specific formula is shown in the description.

A simple, efficient, and environmentally friendly approach for the synthesis of flavones, aza-flavones, and aza-flavanones from corresponding 2′-hydroxy or 2′-aminochalcones has been developed. The reactions are successfully conducted in presence of silica-gel-supported Ce(SO4)2·4H2O under solvent-free conditions.
