A Rh(III)-catalyzed strategy involving the [4+1] annulation of 2-arylphthalazine-1,4-diones with α-diazo carbonyl compounds was developed, accessing a series of unprecedented hydroxy-dihydroindazolo-fused phthalazines in ...

Direct oxidative homocoupling of 2-arylimidazo heterocycles was achieved by using a phenyliodine diacetate-mediated BF3·OEt2-accelerated protocol at room temperature. A series of biimidazo heterocycles were synthesized ...

An efficient approach towards peptide synthesis that allows easy access to variety of small peptides via one-pot aziridine-mediated ligation/desulfurization strategy has been described. The protocol afforded a library of ...

A library of bile-acid-appended triazolyl aryl ketones was synthesized and characterized by detailed spectroscopic techniques such as 1H and 13C NMR, HRMS and HPLC. All the synthesized conjugates were evaluated for their ...

N-Hydroxyamidoximes, N-aminoamidoximes, and hydrazidines belong to a class of compounds with the general formula RC═NX(NHY) where X = OH or NH2, Y = OH or NH2, and R is a linear side chain, carbocycle residue, or heterocycle ...

Direct aerobic oxidative cross-dehydrogenative coupling of aryl acetaldehydes at C-3 position of imidazoheterocycles via copper catalyzed reaction resulted in the synthesis of dicarbonylated imidazoheterocycles in 55–85% ...

A mild, efficient, ligand free and environmentally benign approach towards the construction of sp2 C-sp3 N bond has been developed via copper catalysed Ullmann type of coupling between 4-chlorocoumarin with N-terminus ...

A series of novel spiro[indole-thiazolidine]spiro[indole-pyran] derivatives were synthesized from N-(bromoalkyl)indol-2,3-diones via monospiro-bisindole intermediates; the two indole nuclei being connected via N–(CH2)n–N ...

Mercury pollution is a widespread danger to human health and environment. Due to limitations associated with the existing Hg2+ chemosensors, development of new, efficient and selective chemosensors capable of sensing mercury ...

The mechanical properties of crosslinked polymers depend on their structural features, one of which is the functionality of the crosslinks in a polymer network. To study the effect of crosslink functionality (ϕ) on the ...
