Access to Indole-Fused Polyheterocycles via Pd-Catalyzed Base-Free Intramolecular Cross Dehydrogenative Coupling

Journal of Organic Chemistry, 2016
A base-free process to access indole-fused polyheterocycles via a highly efficient and atom-economic palladium-catalyzed intramolecular cross dehydrogenetive coupling (CDC) reaction of 4-aniline substituted coumarins, quinolinones, and pyrones has been developed.

Construction of Fused Polyheterocycles through Sequential [4 + 2] and [3 + 2] Cycloadditions

Organic Letters, 2017
A method for Pd-catalyzed aerobic oxidative reaction of quinazolinones and alkynes has been developed for sequential [4 + 2] and [3 + 2] cycloadditions to assemble a novel fused-polycyclic system containing tetrahydropyridine and dihydrofuran rings. The reaction process involves C-H and N-H bond functionalization for the formation of tetrahydropyridine

A highly efficient synthesis of imidazo-fused polyheterocycles via Groebke–Blackburn–Bienaymè reaction catalyzed by LaCl3·7H2O

Tetrahedron Letters, 2014
A highly efficient and mild protocol for the synthesis of imidazo-fused polyheterocycles via Groebke–Blackburn–Bienayme reaction under the influence of catalytic amount of lanthanum chloride heptahydrate has been described. A wide range of nitrogen-enriched polyheterocycles are synthesized with high yields under neat conditions.

Synthesis of 1,2,3‐Fused Indole Polyheterocycles by Copper‐Catalyzed Cascade Reaction

European Journal of Organic Chemistry, 2018
A one‐pot reaction has been devloped for the preparation of 1,2,3‐fused indole polyheterocycles by starting from 2‐iodobenzamide and 2‐iodobenzyl cyanide in the presence of a copper catalyst. The cascade process involves the efficient formation of one C–C and three C–N bonds.
