Organocatalyticasymmetric Michael addition between 3-substituted oxindoles and enals catalyzed by chiral camphor sulfonyl hydrazines (CaSHs) has been developed. A wide range of 3-substituted oxindoles and enals were successfully used, giving the corresponding 3,3-disubstituted oxindoles containing vicinal stereogenic carbon centers in good yields with good to excellent enantioselectivities and moderate

The present invention relates to the compounds of formula (I) and pharmaceutical compositions containing these compounds. The compounds provided herein can act as maxi-K potassium channel openers, which makes them suitable for use in therapy, particularly in the treatment or prevention of fragile X associated disorders, such as fragile X syndrome.
Demonstrated herein is the construction of trifluoromethylated quaternarycarboncenters by an asymmetric radical transformation. Enantioenriched trifluoromethylated oxindoles were accessed using a hypervalent iodine‐based trifluoromethyl transfer reagent in combination with a magnesium Lewis acid catalyst and PyBOX‐type ligands to achieve up to 99 % ee and excellent chemical yields.
