scandium(III)/indapybox complex with tetrakis‐[3,5‐bis(trifluoromethyl)phenyl]‐borate (BArF) to enhance catalytic activity and control stereoselectivity. Functionalized cyclopentanes containing a quaternary carbon center are derived from alkylidene oxindole, coumarin, and malonate substrates with high stereoselectivity. The enantioselective 1,4‐conjugate addition and enantioselective lactone formation
