Nanocrystalline Copper(II) Oxide–Catalyzed One-Pot Synthesis of Imidazo[1,2-a]quinoline and Quinolino[1,2-a]quinazoline Derivatives via a Three-Component Condensation
摘要:
A simple, efficient, and practical procedure for the synthesis of imidazo[1,2-a]quinoline and quinolino[1,2-a]quinazoline derivatives using CuO nanoparticles as a novel catalyst in excellent yields is described. The catalyst can be recovered conveniently and reused at least four times without any loss of activity.

Efficient domino approaches for the synthesis of multifunctionalized tricyclic fused pyrroles and dibenzo[b,e][1,4]diazepin-1-ones have been established. The reaction pathways were controlled by varying enaminones with different substituted patterns to give a series of new fused pyrroles and dibenzo[b,e][1,4]diazepin-1-ones selectively. The complete anti diastereoselectivity was achieved for the first
