资源简介：
The first organocatalytic and asymmetric direct vinylogous Michael reaction that employs the electron-deficient vinyl malononitriles as the nucleophilic species has been reported. The novel transformations exhibit exclusive γ-selectivity and high diastereo- and enantioselectivity in the addition to nitroolefins, which give the multifunctional products with two vicinal chiral centers.
