Direct allylic etherification of unactivated alcohols occurs regio- and stereoselectively under mild, gold(I)-catalysed conditions.
The use of palladium catalysts for the oxidation of alcohols to aldehydes and ketones in the presence of various types of reoxidants is well known. Recently, the advantages of using molecular oxygen as the oxidant in the Pd-catalyzed oxidation of alcohols have been explored. The aim of this review is to provide an overview on the most important homogeneous palladiumcatalyzed aerobic oxidation o...
1. The activity of liver alcohol dehydrogenase with propan-2-ol and butan-2-ol has been confirmed. The activity with the corresponding ketones is small. Initial-rate parameters are reported for the oxidation of these secondary alcohols, and of propan-1-ol and 2-methylpropan-1-ol, and for the reduction of propionaldehyde and 2-methylpropionaldehyde. Substrate inhibition with primary alcohols is ...
Lipase-catalyzed kinetic resolution of aryltrimethylsilyl chiral alcohols through a transesterification reaction was studied. The optimal conditions found for the kinetic resolution of m- and p-aryltrimethylsilyl chiral alcohols, led to excellent results, high conversions (c = 50%), high enantiomeric ratios (E > 200) and enantiomeric excesses for the remaining (S)-alcohol and (R)-acetylated pro...
context viral hepatitis and the consumption of alcohol are recognized as important reasons for the development of liver disease throughout the world. it would also seem that chronic alcoholism causes more severe and rapid progression of liver disease in patients with chronic hepatitis c, leading to more frequent liver cirrhosis and hepatocellular carcinoma. evidence acquisition the data for thi...
background: statistics of alcohol use iran was investigated in the beginning of 2010 in mental, social health and addiction department of ministry of health. the findings showed that the alcohol use, especially in young people, is notable. hence a strategic plan or a policy document in alcohol use was needed to explain the main vision also provide countrywide strategies for all related domains ...
The development of new synthetic fluorination reactions has important implications in medicinal, agricultural, and materials chemistries. Given the prevalence and accessibility of alcohols, methods to convert alcohols to trifluoromethanes are desirable. However, this transformation typically requires four-step processes, specialty chemicals, and/or stoichiometric metals to access the trifluorom...
