Nitrones are key intermediates in organic synthesis. Herein, we report the first photo‐redox synthesis of methylene nitrone intermediates from nitroarenes and arylamines. The highly reactive methylene nitrones are in situ trapped by alkenes to afford various isoxazolidines. This three‐component reaction features the use of N,N‐dimethylanilines or N‐aryl glycines as C1 building blocks, which allow for
Hydrazide compounds with GPCR desensitization inhibitory activity are provided that may be used to influence, inhibit or reduce the action of a G-protein receptor kinase. Pharmaceutical compositions including therapeutically effective amounts of the hydrazide compounds and pharmaceutically acceptable carriers are also provided. Various methods using the compounds and/or compositions to affect disease states or conditions controlled or influenced by GPCRs are also provided. Various methods using the compounds and/or compositions to affect disease states or conditions such as cancer, osteoporosis and glaucoma are also provided.
A decarboxylative cross-coupling reaction of α-aminoacids with nitrones via visible-light-induced photoredox catalysis has been established for easy access to β-amino hydroxylamines and vicinal diamines with structural diversity, which is featured with simple operation, mild conditions, readily available α-aminoacids, and a broad scope of nitrone substrates. The application of this protocol can furnish
