An efficient procedure has been developed for the preparation of tetrasubstituted unsymmetrical 1,4-enediones via copper-promoted autotandem catalysis and air as the oxidant. Various N-nucleophiles are compatible with this reaction, such as morpholine, piperidine, pyrrolidine, arylamines, pyrazole, imidazole, benzimidazole, and benzotriazole. This reaction also has significant advantages in eas...
The title compound, C(18)H(20)N(2)O(2), crystallizes with two mol-ecules in the asymmetric unit. The morpholine rings of both mol-ecules adopt chair conformations. The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds. One phenyl ring is disordered over two orientations in a 0.665 (5):0.335 (5) ratio.
