The present invention provides Ras modulators including inhibitors and/or antagonists of Ras, Ras binding, and Ras-dependent cell signaling activity. Also provided are methods of utilizing the Ras modulators as therapeutics.
Herein we report the nickel-catalyzed reductive dicarbofunctionalization of 1,1-disubstituted enamides with unactivated alkyl iodides to access the 3,3-dialkyl-substituted isoindolinone frameworks. This tandem cyclization/reductive coupling protocol exhibits broad functional group tolerance under mild conditions. The utilization of commercially accessible chiral Bn-Biox ligand allows excellent enantioselectivities

The enantioselective reductive dicarbofunctionalization of internalalkenes has been developed to enable the formation of vicinal stereogenic centers. This protocol allows for facile synthesis of chiral pyrrolidinones bearing vicinal or quaternary stereocenters with excellent enantio- and diastereoselectivities. DFT calculations suggest that the enantiodetermining step is intramolecular migratory insertion
The desymmetric dicarbofunctionalization of unactivatedalkenes by a nickel-catalyzed reductive cross-coupling reaction has been developed to access pyrrolidinones bearing multi-stereocenters with broad functional-group tolerance. The utilization of the 8-Quinox ligand is crucial for maintaining high enantio- and stereoselectivities.
