A C-H functionalization strategy for the expedient access to photoreactive chemical probes of commonly found heterocyclic fragments or drug molecules of pharmaceutical relevance is described. A series of aryl glyoxylic acid reagents featuring pendant alkyne or azide clickable handles have been developed for application in the radical-mediated appendage of benzoyl fragments onto simple heteroaromatic

4-azidobenzoylformate was reacted with 56 mono- and diynes. After hydrolysis of the methyl esters, the resulting alpha-ketocarboxylic acids were assayed in crude form against the Yersinia PTP and PTP1B. Four compounds were selected for further evaluation, and one compound was chosen as the lead for generation of the second round library. This lead compound was modified by conversion of an alcohol into an azide group
