The phenyliodonium ylide of 2-hydroxy-1,4-naphthoquinone reacts with aminoesters, ureas, aminoalcohols and aminophenols in refluxing dichloromethane to afford good yields of indanedione 2-carboxamido compounds, that in solution exist in an enol-amide form. The same reactants in a copper-catalyzed reaction afford mainly the corresponding N-arylo compounds. Arylhydrazines are mainly oxidized by the ylide and arylation occurs only in a low yield.

Proto-oncogene c-Myc plays an essential role in the development of colorectal cancer (CRC), since downregulation of c-Myc inhibits intestinal polyposis, which is the most cardinal pathological change in the development of CRC. Herein, a series of novel phenoxy-N-phenylaniline derivatives were designed and synthesized. The cytotoxicity activities of all the derivatives were measured by MTT assay in different colon cancer cells, 4-(3,5-dimethoxy-4-(((4-methoxyphenethyl)amino)methyl)phenoxy)-N-phenylaniline (42) was discovered, the lead compound 42 with excellent cytotoxicity activity of IC50 = 0.32 μM, IC50 = 0.51 μM, in HT29 and HCT 15 cells, respectively. Compound 42 had a good inhibitory activity of c-Myc/MAX dimerization and DNA binding. Besides, compound 42 could effectively induce apoptosis and induced G2/M arrest in low concentration and G0/G1 arrest in high concentration to prevent the proliferation and differentiation in colon cancer cells. Western blot analysis confirmed the 42 strongly down-regulated expression of c-Myc. Furthermore, during 30 days treatment 42 exhibited excellent efficacy in HT29 tumor xenograft model without causing significant weight loss and toxicity. Consequently, 42 could be a promising drug candidate for CRC therapy.

An efficient and versatile oxidative coupling reaction was developed for the synthesis of valuable β-functionalized unsaturated ketones and meta-substituted phenols. In the case of intramolecular reactions, achieving rapid molecular complexity through multiple dehydrogenative couplings is already a well-established strategy. Herein, we report an intermolecular multiple dehydrogenative coupling between ketones and nucleophilic amines or boronic acids using inexpensive copper(I) oxide as a catalyst. This method provides a facile access to highly desirable chemical products such as α,β-unsaturated ketones, enaminones, and synthetically relevant meta-substituted phenols. (Figure presented.).
