thiourea-catalyzed asymmetricsynthesis of highly enantioenriched spirocyclopentaneoxindoles containing chiral amide functional groups using simple 3-substituted oxindoles and nitrovinylacetamide as starting materials was achieved successfully. This protocol features operational simplicity, highatomeconomy, and highcatalytic asymmetry, thus representing a versatile approach to the synthesis of highly enantioenriched

This invention relates to 1,3-cyclohexanedione derivatives and 1,3-cyclopentanedione derivatives that have buffering function in non-aqueous solutions and to the use thereof for tuning the conditions to control chemical events in non-aqueous solutions. One aspect of the invention is a method for buffering a non-aqueous solution, including adding a buffering molecule to the non-aqueous solution, in which the non-aqueous solution contains an organic solvent, the buffering molecule is a 1,3-cyclohexanedione derivative or a 1,3-cyclopentanedione derivative, and the buffering molecule is optionally conjugated to a solid support.

pharmaceuticals. An appealing method for accessing 2-oxindoles is by oxidation of the corresponding indole, a transformation currently executed using stoichiometric quantities of unsafe chemical oxidants that can also form unwanted side-products. Herein, we report that 3-substituted indoles undergo a logistically straightforward, electrochemical oxidation to the corresponding 2-oxindole in the presence of potassium
