A novelrearrangement of N-hydroxy indole derivatives obtained from addition of N-hydroxy indoles to the activated triple bonds of alkynes was found to coexist with 3,3-sigmatropic rearrangements to the indolic ring. A mechanism involving an intermediate oxaziridinium ring rationalizes the transformation.
In its many embodiments, the present invention provides a novel class of indolines as inhibitors of α2C adrenergic receptor agonists, methods of preparing such compounds, pharmaceutical compositions containing one or more such compounds, methods of preparing pharmaceutical formulations comprising one or more such compounds, and methods of treatment, prevention, inhibition, or amelioration of one or more conditions associated with the α2C adrenergic receptors using such compounds or pharmaceutical compositions.
