Copper mixed oxide NPs supported on a hematite surface were achieved using a facile hydrothermal method in a single step. The catalytic potential of the Cu@Fe2O3 NPs was explored for the synthesis of aminoindolizines and pyrrolo[1,2-a]quinolines.

CuCl catalyzes efficient synthesis of aminoindolizine scaffolds by one-pot reactions in PEG of pyridine- or quinoline-2-carboxaldehydes with secondary amines and terminalalkynes via tandem C–H activation, coupling, and cyclization reactions. The reactions are easy to perform, atom-economic, environment friendly, broad in scope, and allow the generation of a number of biologically potent aminoindolizine
ZnI2 was found to be an efficient catalyst for the synthesis of indolizine derivatives by a three-component coupling of pyridine-2-carboxaldehyde/quinoline-2-carboxaldehyde, secondary amines, and terminal alkynes in high yields. This protocol is compatible with a wide range of substrates and is expected to find broad applications due to its operational simplicity, shorter reaction time and low cost
发现ZnI 2是通过吡啶-2-羧醛/喹啉-2-羧醛,仲胺和末端炔烃的三组分偶联以高收率合成吲哚嗪衍生物的有效催化剂。该协议可与多种基材兼容,并且由于其操作简便,反应时间短和成本低廉,有望被广泛应用。初步的光物理研究表明,合成的吗啉代吡咯并[1,2- a ]喹啉代表了一类新的具有高量子产率的荧光团。

A goid(III)-catalyzed multicomponent coupling/cycloisomerization reaction of heteroaryl aldehydes, amines, and alkynes under solvent-free conditions or in water has been developed. This methodology provides rapid access to substituted aminoindolizines with high atom economy and high catalytic efficiency. Especially, the coupling of enantiomerically enriched amino acid derivatives produces the corresponding N-indolizine-incorporated amino acid derivatives without loss of enantiomeric purity.

temperature without any catalyst. Moreover, both types of products can be obtained in onepotfrom commercial materials as well as at a gram scale. It is worthy of note that the regioselectivity of the β‐enaminones is inaccessible by the standard literature methods and their utility has been exemplified in the synthesis of diverse heterocycles. We have made every endeavor to put forward the corresponding
