  Synthetic probes for detecting the activity of enzymes that catalyze reactions of post-translationally modified cysteine residues are described. The probes include “turn-on” probes that include a carbamate linkage that is cleaved via an intramolecular reaction with a free thiol produced by an enzyme catalyzed activity. The probes also include ratiometric, Michael addition-based probes that respond to enzymatic activity by a change in structure that results in a change in fluorescence properties. Methods of using the probes to detect enzymatic activity and disease are described. For example, the probes can be used to detect enzymatic activity in a variety of samples, including live cells and heterogeneous tissues. In addition, prodrugs that can be activated by enzymes that catalyze reactions of post-translationally modified cysteine residues and methods of using the prodrugs to treat disease are described.

  heterocycles has been realized via C(sp3)‐centered radical C(sp2)−C(sp3) bond formation under oxidant‐free conditions at room temperature. This reaction readily incorporates various functional alkyl groups into heterocyclic compounds without observation of any alkyl radical rearrangement and represents a mild and general tool for the preparation of valuable alkyl group‐functionalized heterocyclic compounds.

  在阳光或蓝色LED的照射下，室温下无氧化剂条件下，通过以C（sp 3）为中心的自由基C（sp 2）-C（sp 3）键形成，实现了各种非芳族杂环的区域选择性脱羧烷基化。该反应很容易将各种官能团的烷基结合到杂环化合物中，而没有观察到任何烷基自由基的重排，这是制备有价值的烷基官能化的杂环化合物的温和而通用的工具。

  An efficient photocatalytic decarboxylative 3-position alkylation of coumarins by using alkyl N-hydroxyphthalimide esters as alkylation reagents has been developed. A variety of NHP esters derived from aliphatic carboxylic acids (primary, secondary, and tertiary) has been proved to be tolerated for this decarboxylation process, affording a broad scope of 3-alkylated coumarin derivatives in moderate
