9-Amino-9-deoxyepiquinine efficiently catalyzed the double-conjugate addition of malononitrile to dienones. A number of 1,1,2,6-tetrasubstituted cyclohexanones were prepared in good yields, diastereoselectivities, and excellent enantioselectivities.

the construction of quaternarycarboncenters is reported. Glucoamylase from Aspergillus niger (AnGA) was used as a sustainable and eco-friendly catalyst. Various highly substituted trans-cyclohexanones with a quaternarycarboncenter were obtained with yields of up to 92%. As a novel case of enzyme promiscuity, this work provides a bio-catalytic alternative for construction of quaternarycarbon centers
