A synthesis of carboxylic esters from various carboxylic acids and alcohols is successfully carried out by using a condensation reagent, pyridine-3-carboxylic anhydride (3-PCA). This reaction materialized synthesis of various carboxylic esters to be carried out under mild conditions by simple experimental procedure.
An iodosylbenzene - iron tetraarylporphyrin catalyst system decarboxylated α-aryl carboxylic acids and α,α,α-trisubstituted aceticacids efficiently to give the corresponding alcohol and carbonyl derivatives.
Phosphorofluoridic acid with an L-menthyl group catalyzed condensation reaction between carboxylic acids and 1-arylalkyl alcohols under solvent-free conditions to give esters in moderate to high yi...

The parallel kinetic resolution of racemic 1-phenylethanol using an equimolar combination of quasienantiomeric 2-arylpropionic and butanoic acids mediated by a N,N'-dicyclohexylcarbodiimide (DCC)/3,5-lutidine coupling is discussed. The levels of diastereoselectivity were high leading to separable quasi-enantiomeric esters in good yield. (C) 2008 Elsevier Ltd. All rights reserved.
