A tris(pentafluorophenyl)borane-catalyzed oxidation reaction of α-diazoesters (α-diazo amides) with dimethyl sulfoxide has been developed. The reaction proceeds under metal free conditions to afford a series α-ketoesters and α-ketoamides. The synthetic utility of this protocol is demonstrated through synthetic transformations and scaled-up synthesis. (Figure presented.).

An enantioselective, catalytic trichloromethylation of 2-acyl imidazoles and 2-acylpyridines is reported. Several products are formed with enantiomeric excess of ≥99%. In this system, a chiral iridium complex serves a dual function, as a catalytically active chiral Lewis acid and simultaneously as a precursor for an in situ assembled visible-light-triggered photoredox catalyst.

A convenient four-step preparation route to novel 7-chloro-imidazo[2,1-b][1,3]thiazin-5-ones is presented, starting from methyl phenylglyoxylate. A unique feature of this synthesis is a heterocyclization strategy, in which a halogen atom is introduced alr
A novel approach to the synthesis of 2-aryl propionates

A two step conversion of phenyl glyoxylates to 2-aryl-propionates has been accomplished. Esters of phenylglyoxylic acid have been converted to corresponding β,β-dichlorostyrenes. These on further reduction gave esters of 2-arylpropionic acids.
