A cycloisomerization of enynes with a benign calcium catalyst is presented exploring a complementary reactivity to that usually found in transition and noble metal‐catalyzed reactions. Thereby, a systematic investigation of the π‐activation of alkynes with reactive carbocations has been realized and ketones of various ring sizes were easily accessed. We are certain that these basic investigations will
Purine derivatives that inhibit cellular necroptosis and/or human MLKL, pharmaceutical compositions thereof, and methods of treating an MLKL-mediated disorder with an effective amount of the compound or composition. Said MLKL-mediated disorder is pathology associated necroptosis, including ischemia-reperfusion damage, neurodegeneration, and inflammatory diseases such as acute pancreatitis, multiple sclerosis, inflammatory bowel disease, and allergic colitis.
