Nano KF/Clinoptilolite: An Effective Heterogeneous Base Nanocatalyst for Synthesis of Substituted Quinolines in Water
摘要:
A proficient, green and environmentally benign one-pot three-component synthesis of functionalized quinolines was developed by condensation reactions of isatin, activated acetylenic compounds, and alcohols in the presence of KF/CP (NPs) as a heterogeneous base nanocatalyst, at room temperature in water.[GRAPHICS]

The selective reduction of 3,4-dicarbomethoxyquinoline by lithiumaluminium hydride at low temperature affords only the unexpected 3-formyl 4-carbomethoxy quinoline. The difficulty of reduction of the usually more reactive 4-ester group can be explained by a steric hindrance by the H5, peri proton on one side and by the 3-ester group on the other side.
