The invention of radical reactions. Part XXXIV. Homologation of carboxylic acids to α-keto carboxylic acids by Barton-ester based radical chain chemistry
Carboxylicacids can be transformed into the homologous α-ketoacids by Barton-esterbasedradicalchemistry. This method was especially successful when ethyl α-trifluoroacetoxy acrylate was used as a radical trap.
