A study of the photochemistry of 4-acetyl- and 4-benzoyl-5-methyl-1,2,3-triazoles shows that the nature and lifetime of the lowest triplet state depends on the nature of the 1- and 4-substituents. 4-Benzoyl-5-methyl-1,2,3-triazole has a high rate constant for triplet deactivation, which is attributed to interaction of the nitrogen lone pairs with the excited carbonyl function. The compound forms a pinacol derivative when irradiated in propan-2-ol and undergoes cycloaddition, involving the carbonyl group, with 2-methylpropene, giving an oxetane derivative. 

This enzyme [EC 1.2.1.10] catalyzes the oxidation of acetaldehyde in the presence of NAD+ and coenzyme A to form acetyl-CoA -i- NADH + H+. Other aldehyde substrates include glycolaldehyde, propanal, and bu-tanal. 

Acetyl-4-hydroxy-2H-l,3-thiazine-2,6-diones 61 react with primary amines to give Schiff bases 49. These products are stable under conditions of excess base and prolonged heating in boiling propan-2-ol (Equation 9) <2005RJC134, 2003TL5279>. 

The Pd-catalyzed amidocarbonylation was used for the synthesis of a-arylglycines that are antimicrobial agents and enzyme inhibitors.Thus, iV-acyl-a-arylglycines and other iV-acyl-a-amino acids were synthesized in highly efficient and economical manner under the standard conditions. In a similar manner, an advanced intermediate for the synthesis of antiepileptic Levetiracetam 7, iV-acetyl-a-aminobutyric acid 6, was synthesized in high yield from propanal and acetamide (Equation (1)). ... 

Following oral administration of 50 mg/kg bw 2,3-dibromopropan-l-ol to male Sprague-Dawley rats, two urinary mercapturic acid metabolites were identified as N-acetyl-5 -(2,3-dihydroxypropyl)cysteine and A, W-bis-acetyl-N<5"-(l,3-bis-cysteinyl)-propan-2-ol, respectively. It was inferred that 3-bromo-l,2-propane epoxide is an intermediate in the metabolism of 2,3-dibromopropan-l-ol. In addition, (3-bromolactate was produced, presumably as a result of hydrolysis to the a-bromohydrin and subsequent oxidation (Jones Fakhouri, 1979). Marsden and Casida (1982) identified small amounts of 2-bromoacrylic acid in the urine of rats injected intraperitoneally with 2,3-dibromopropan-l-ol and suggested that this arose by oxidation and dehydrobromi-nation, with 2-bromoacrolein as an unstable intermediate. 

Rats receiving single oral doses of l,2-dichloro[l- C]propane excreted about 50% in the urine and 5% in faeces in 24 h. There was little further excretion over the next 72 h. A total of 19% of the dose was excreted as CO2 and 23% as other volatile substances. At 96 h, 5% remained in the carcass. The major urinary metabolite found after oral dosing was A-acetyl-V-(2-hydroxypropyl)-L-cysteine. Identified minor metabolites were P-chlorolactate and /V-acet l-.S -(2,3-dihydroxypropyl)-r,-cysteine (lARC, 1986). 

An interesting intramolecular cyclization takes place when 1,3-di-(2-pyridyl)-propane-l,3-diol is treated with sodium acetate in refluxing acetic acid.93 l-Acetyl-3-(2-pyridyl)indolizine is formed in 30% yield. Support for the proposed mechanism, shown in Scheme 14, is the observed increase in yield when the reaction is subjected to UV irradiation, which would be expected to increase the proportion of the ds-olefin present. 

Purify of the crude residue by flash chromatography on silica gel using petroleum ethenethyl acetate (98 2) as eluent to obtain pure r-1-acetyl-1-ethyl-f-2-phenylcyclo propane (19 trans cis = 7.7 1) (0.103 g, 80%) as a clear oil. Characterize the product by 1H NMR, IR spectroscopy, and HRMS spectroscopy.
