Qian, Yong published the artcileActivity-Based Proteome Profiling Probes Based on Woodward’s Reagent K with Distinct Target Selectivity, Application In Synthesis of 7064-33-7, the main research area is protein profiling Woodward reagent K derivative; activity-based probes; fluorescent imaging; protein labeling; proteomics.

Woodward’s reagent K (WRK) is a reactive heterocyclic compound that has been employed in protein chem. to covalently and unspecifically label proteins at nucleophilic amino acids, notably at histidine and cysteine. The authors have developed a panel of WRK-derived activity-based probes and show that surprisingly and unexpectedly, these probes are fairly selective for a few proteins in the human proteome. The WRK-derived probes show unique reactivity towards the catalytic N-terminal proline in the macrophage migration inhibitory factor (MIF) and can be used to label and, if equipped with a fluorophore, to image MIF activities in living cells.

Debbarma, Suvankar published the artcileHarnessing Stereospecific Z-Enamides through Silver-Free Cp*Rh(III) Catalysis by Using Isoxazoles as Masked Electrophiles, Application In Synthesis of 7064-33-7, the main research area is stereospecific enamide preparation rhodium catalyzed carbon hydrogen functionalization; salicylaldehyde isoxazole reaction masked electrophile.

The stereospecific synthesis of Z-enamides is described in this paper. For the first time, isoxazoles have been employed as electrophiles in C-H functionalization to afford thermodynamically less stable Z-enamides utilizing salicylaldehydes in an atom- and step-economic fashion. The stereochem. of enamides might originate from the relative disposition of atoms present in isoxazole and the intramol. hydrogen bonding. The reaction showed excellent scope as several structurally and electronically diverse salicylaldehydes and isoxazoles reacted efficiently.
