Heterocycles are found to be present as the fundamental core compositions of many natural
products, agrochemicals, and pharmaceuticals. Among all, the nitrogen-containing …

Direct functionalization of heterocycles using C− H activation widely relies on the precious
metal complexes. In past decade, the use of earth abundant and inexpensive transition …

A comparative study of C8-alkylation of isoquinolone with maleimides is reported under
different catalytical systems. Among different catalytical systems, Ru and Rh catalysts were …

Herein we report Cp* Co (III)-catalyzed site-selective (C8)–H olefination and oxyarylation of
quinoline N-oxides with terminal alkynes. The selectivity for C8-olefination and oxyarylation …

An efficient Rh (III)‐catalyzed C− H alkenylation of N‐protected isoquinolone with
maleimides is reported. The carbonyl group of isoquinolone acts as an inherent directing …

Co (III)-catalysed site-selective C8-allylation and vinylation of isoquinolones with allyl
acetate and vinyl acetates has been accomplished. The oxo group of isoquinolone has been …

A regioselective annulation protocol of N‐chlorobenzamide with allenes and vinyl acetate is
reported using a less expensive catalytic system, ie Co (III) catalysis and Na2CO3 as …

A Cu (OTf) 2-mediated regioselective dearomative aryl-hydroxylation across the C (sp2) N
bond of 2-aryl quinoxalines and bis-N-arylation of (benz) imidazoles were developed using …

A versatile Co (III)-catalyzed C6-selective C–H activation/pyridine migration of 2-pyridones
with available propiolates as coupling partners was demonstrated. This method features …

A sustainable protocol for Ru (II)-catalyzed regioselective C (sp2)–H methylation of indolines
in the presence of ethanol has been explored. A wide array of substituted indolines were …
