Outstanding glutathione chemosensing selectivity with a new coumarin-based probe is reported and discussed in the context of live cell experiments; the point of attack is flanked by two proximal carbonyl groups.
A highly efficient protocol is reported for the synthesis of chiral β-seleno amines via the ring-opening reaction of aziridines. Under neutral conditions, employing a stable phenyl selenolate specie (PhSeZnBr) and (BMIM)BF4 as solvent, β-seleno amines were obtained in good to excellent yields. Reuse of the ionic liquid was also possible, and four runs were performed with no decrease in the yields.
