Construction of Nonadjacent Stereocenters Containing a Trifluoromethylated Carbon by Organocatalyzed Michael Addition of beta-Ketoesters to 2-(Trifluoromethyl)acrylate
The first enantioselective construction of nonadjacent 1,3-tertiary-quaternary stereocenters containing a trifluoromethylated carbon by cinchona alkaloid-catalyzed Michael addition of beta-ketoesters to 2-(trifluoromethyl)acrylate has been achived in high yields with high enantioselectivities up to 97% ee.
