acetophenone derivativesWe present the results of femtosecond optical heterodyne-detected optical Kerr effect spectroscopy (OHD-OKE) on acetophenone and its derivatives: o -hydroxybenzaldehyde, o -methylacetophenone, and o -hydroxyacetophenone. The depolarized Raman scattering spectra were also measured,...

Synthesis of [5-(4-substituted-benzylidene)-2,4-dioxothiazolidin-3-yl]acetic acid (1-phenylethylidene)hydrazides (5a–e) Equimolar quantities (6 mmol) of substituted-benzylidene thiazolidine -2,4-dione hydrazides (4a–e) and acetophenone were dissolved in absolute ethanol (50 mL), followed ...
2.1.2.1. Synthesis of chalcones 15–17 For the synthesis of intermediate acetophenones 12–14, 3,3-dimethylallyl bromide (1.5 mmol) was added to a solution of corresponding acetophenone (1 mmol) and potassium carbonate (2 mmol) in anhydrous acetone (10 mL). The mixture was kept...
Chromatography-mass spectrometry of molecular metabolites in the expired air of resting healthy humans has been used to identify oxyketones, mainly l-hydroxy-2 propanone (acetol), aldehydes (decenal, benzaldehyde), acetophenone, phenol, ... RG Mardanov,OI Orlov,AA Markin,... - 《Human Physiol...
Scheme 1. Synthesis of intermediates 3A–3C. The thiouracil intermediates (3A–3C) were then chlorinated (Scheme 2) using the POCl3/PCl5 mixture giving active chloropyrimidine derivatives (4A–4C). These chloro compounds reacted with p-aminoacetophenone in pyridine as a solvent and base yieldin...
According to Scheme 1, a new series of pyrazolo-oxothiazolidine derivatives was synthesized in three steps. Initially, the Claisen–Schmidt condensation of acetophenone or para-methoxy acetophenone (1a, b) and aromatic aldehydes (2a–2h) in the presence of sodium hydroxide in ethanol resulted in...
