The synthesis of novel 3-tetrazolylmethyl-4H-chromen-4-ones via an Ugi-azide
multicomponent reaction and their biological evaluation against Entamoeba histolytica …

The first synthetic strategy for nonsymmetrical 3, 3 ″-biflavones is described. To this end, a
novel visible-light iridium-catalyzed radical C-3 alkylation of flavones with o-methoxy …

The conversion of an alcohol‐based functional group, into a trifluoromethyl analogue is a
desirable transformation. However, few methods are capable of converting O‐based …

An expeditious route involving a Pd-catalyzed intramolecular biaryl-coupling for the
synthesis of the N-methyl-5, 6-dihydrobenzo [c] phenanthridine scaffold has been …

The unusual alcohol mediated formation of 4-oxo-2-aryl-4 H-chromene-3-carboxylate
(flavone-3-carboxylate) derivatives from 4-hydroxycoumarins and β-nitroalkenes in an …

Xanthate-based radical chemistry was used for the regioselective direct alkylation of
caffeine, uracil, and imidazo [1, 2-a] pyridine systems, using dilauroyl peroxide as initiator …

Natural medicines are a valuable resource for the development of new drugs. However,
factors such as low solubility and poor bioavailability of certain constituents have hindered …

A convenient, high yielding synthesis of oxindoles by metal-free di-functionalization of
alkenes with xanthates has been developed. This transformation involves a radical …
