This data article is related to the subject of a publication in Process Biochemistry, entitled "Chloroperoxidase-catalyzed amino alcohol oxidation: Substrate specificity and novel strategy for the synthesis of N-Cbz-3-aminopropanal" (Masdeu et al., 2016) [1]. Here, the products of the chemical reaction involving the amino aldehyde (N-Cbz-3-aminopropanal) and peroxides (tert-butyl hydroperoxide ...
The Chemiluminescence (CL) that accompanies the oxidation of luminol with tert-butyl hydroperoxide (t-BuOOH) in alkaline medium was studied. The reaction occurring between luminol and t-BuOOH in alkaline medium leads to the production of nitrogen gas with simultaneous emission of CL. The effect of non-steroidal anti-inflammatory drugs (NSAIDS) like aspirin and ibuprofen has also been studied. T...
Chlorogenic acid is a well known natural product with important bioactivities. It contains an ester bond formed between the COOH of caffeic acid and the 3-OH of quinic acid. We synthesized a chlorogenic acid analogue, 3α-caffeoylquinic acid amide, using caffeic and quinic acids as starting materials. The caffeoylquinc acid amide was found to be much more stable than chlorogenic acid and showed ...
The rates of oxidation of adenosine and chlorogenic acid by tert-butoxyl radicals (t-BuO) were studied by measuring the absorbance of adenosine at 260 nm and chlorogenic acid at 328 nm spectrophotometrically. t-BuO radicals were generated by the photolysis of tert-butyl hydroperoxide (t-BuOOH) in presence of tert-butyl alcohol to scavenge OH radicals. The rates and the quantum yields (phi) of o...
two new heterogenized epoxidation nanocatalysts based on molybdenum and tungsten compounds were prepared withcovalent grafting of mcm-41 with 3-aminoropropyl trimethoxysilane and subsequent reaction with diphenylphosphinobenzaldehyde and complexation with m (mo, w)o2(acac)2. x-ray diffraction and nitrogen sorption analyses revealed the preservation of the textural properties of the support as w...
covalent grafting of the nanoporous molecular sieve mcm-41 with 3-aminopropyl trimethoxysilane and acetyl acetone (acac) successively gave modified mcm-41 (acacampmcm-41). reaction of the resulted material with glycine afforded the corresponding supported glycine schiff base ligand and subsequent reaction with [bis(acetylacetonato)dioxomolybdenum(vi)] was lead to molybdenum complex supported on...
The macrocyclic ligands 2,3,5,6-Bis{3’-bromo-5’-tert-butyl benzo-5-phenyl benzo} 12C3 (L1), 2,3,5,6-bis{3’-bromo-5’-tert butyl-benzo-5’-phenyl-benzo}15C4 (L2), 2,3,5,6-bis{3’-bromo-5’-tert butyl-benzo-5’-phenyl-benzo}18C5 (L3) have been synthesized and their alkaline metal compounds with NaClO4∙H2O and KClO4 have ...
The oxidation of hydrocarbons is great significance for the chemical industry as it provides access to valuable functionalized chemicals. cyclohexene has raised much interest because enables direct synthesis adipic acid, which an important building block in polymer chemistry. However, selective rather challenging due its two reactive centers so that epoxidation or allylic may occur leading a va...
