Various 2-(substitutedphenylmethyleneimino)aminoacetylmethylene-3-(2′-substitutedindol-3′-yl)-halosubstituted-4(3H)quinazolinones (5a–5i) and 2-(substituted phenylaminomethyleneacetyl-4′-oxo-1′-thiazolidinyl-3-(2″-substi ...

A series of 2-substitutedphenyl-3-(substitutedphenylamino)methyl-2,3-dihydro-4-diphenylamino-1,5-benzoxazepines (4a–4p) and 2-substitutedphenyl-3-substitutedphenylazo-2,3-dihydro-4-diphenylamino-1,5-benzoxazepines (5a–5p) ...

The influence of water/cement ratio and addition of Nano-Silica as partial replacement of cement on the compressive strength and water absorption of mortar mixes is a topic of current research. For this purpose, 32 factorial ...

In an effort to search for more active CNS depressants, a series of spirobarbiturates incorporated with thiazolidinones and azetidinones were synthesized and evaluated for their sedative, hypnotic and anticonvulsant ...

Selective syntheses of S-acyl glutathiones are achieved in 79–98% yields using 1-acyl-1H-benzotriazoles in the presence of potassium bicarbonate in aqueous methanol at 20 °C. N-Acylation of S-(p-nitrobenzoyl) glutathione ...

Amino acid and peptide bioconjugates of niacin I, biotin II, α-tocopherol III and cholecalciferol IV are prepared in good to satisfactory yields by using microwave assistance. In addition, a new benzotriazole-activated ...

Cbz-(protected)-tri- and tetrapeptide conjugates with steroids, sugars, terpenes, and heterocycles were prepared using Cbz-(protected)-tri- and tetrapeptidoylbenzotriazoles as active intermediates.Peptides and their ...

Nα-Boc-Nim-(4-toluenesulfonyl-l-histidylbenzotriazole) enables convenient acylation of N-, O-, S-, and C-nucleophiles with no detectable racemization. We report efficient syntheses of novel histidine-containing di-, tri-, ...

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 ...

Nitrite is quite an abundant anion in the environment. It, however, becomes toxic to human life, as well as aquatic animals when present above the permissible concentration level. We have reported here a Ru(II)-polypyridyl-based ...
