, p. 62 - 65 (2015)
A NaI-mediated α-functionalization of dimethyl malonate and its derivatives with carboxylic acids has been developed. Two different reaction routes based on the same substrates and reaction conditions by simply altering the reaction temperature have been

A practical one-pot three-step sequence is reported for the asymmetric synthesis of α-benzoyloxylated alcohols from primary alcohols. Good overall yields (36-52%) and enantioselectivities (91-94% e.e.) are obtained using a commercial organocatalyst in the key oxylation reaction. A simple modification in the protocol allows the formation of enantioenriched γ-benzoyloxylated α,β-unsaturated ester from alcohol. Synthetic utility has been harnessed to the easy preparation of (-)-γ-octalactone from hexan-1-ol.

Heller, Stephen T.,Sarpong, Richmond
supporting information; experimental part, p. 4572 - 4575 (2010/12/25)
Imidazole carbamates and ureas were found to be chemoselective esterification and amidation reagents. A wide variety of carboxylic acids were converted to their ester or amide analogues by a simple synthetic procedure in high yields.

Peptidylglycine α-amidating monooxygenase catalyzes the biosynthesis of peptide hormones through radical cleavage of the C-terminal glycine residues of the corresponding prohormones. We have correlated ab initio calculations of radical stabilization energies and studies of free radical brominations with the extent of catalysis displayed by peptidylglycine α-amidating monooxygenase, to identify classes of inhibitors of the enzyme. In particular we find that, in closely related systems, the substitution of glycolate for glycine reduces the calculated radical stabilization energy by 34.7 kJ mol -1, decreases the rate of bromination with N-bromosuccinimide at reflux in carbon tetrachloride by a factor of at least 2000, and stops catalysis by the monooxygenase, while maintaining binding to the enzyme.

Reactions of Trialkylsilyl Trifluoromethanesulfonates, VI. - Synthesis of 2-Heterosubstituted O-Alkyl-O-(trimethylsilyl)ketene Acetals and 2-(Trimethylsilyl)carboxylates

Organooxy- and (alkylthio)ethanoic acid esters 2 are silylated by trimethylsilyl triflate (1) in the presence of triethylamine to yield mixtures of ketene acetals 3 and 2-(trimethylsilyl)ethanoates 4.The product distributions 3/4 are governed by the ester groups and the substituents in α position.Cyclic derivatives of 2-hydroxycarboxylic acids 7,9 are silylated by 1/triethylamine to give the ketene acetals 8,10.From N-protected glycine methyl esters 11,12 the ketene acetals 13,15 are obtained in the reaction with 1/triethylamine.

, p. 2777 - 2788 (2007/10/02)
Anodic oxidation of O-benzoylated α-hydroxyacetic acid 1 at graphite electrodes in methanol leads to the corresponding mixed acylals 2 and methyl benzoates 3.The rate 2:3 depends on the substitution of the aromatic ring and can be correlated to Hammett's ?-values.
