Highly Stereoselective Synthesis of 1,2,3-Trisubstituted Indanes via Oxidative N-Heterocyclic Carbene-Catalyzed Cascades
摘要:
Three stereocenters are formed in the carbene catalyzed cascade reaction of enals with various beta-diketones to give the corresponding indane derivatives with excellent stereoselectivities. The products are readily transformed to the corresponding 1,2,3-trisubstituted indane derivatives, which represent privileged substructures in medicinal chemistry.
