Ionic Reactivity of 2-Isocyanoaryl Thioethers: Access to 2-Halo and 2-Aminobenzothia/Selenazoles

An ionic cascade insertion/cyclization reaction of thia-/selena-functionalized arylisocyanides has been successfully developed for the efficient and practical synthesis of 2-halobenzothiazole/benzoselenazole derivatives. This synthetic protocol, incorporating a halogen atom when forming the five-membered ring of benzothia/selenazoles, is different from the existing ones, where halogenation of the preformed benzothia/selenazole precursors happens. Additionally, a facile access to 2-aminobenzothiazoles is also achieved by the one-pot cascade reaction of 2-isocyanoaryl thioethers, iodine, and amines.

Copper(ii) ions supported on functionalized graphene oxide: an organometallic nanocatalyst for oxidative amination of azolesviaC-H/C-N bond activation

Graphene oxide (GO) was chemically modified withpara-aminobenzoic acid (PABA) to immobilize copper(ii) ions on its surface and used as a nanocatalyst for the oxidative C(sp2)-H bond amination reaction. A practical method to prepare Cu2+supported onpara-aminobenzoic acid grafted on GO was reported. The prepared Cu2+@GO/PABA was characterized by FT-IR, XRD, SEM, AFM, TEM, UV-Vis, and ICP techniques. The results showed that the morphology, distribution, and loading of copper ions could be well-adjusted by grafting of PABA on GO. Moreover, just 2 mol% of Cu2+@GO-PABA could catalyze the C-H activation reaction of benzoxazole and benzothiazole with secondary amines in >94% yields. Also, the catalyst showed very good recyclability and much less leaching of the Cu into the reaction solution. The high activity of Cu2+@GO-PABA can be ascribed to the good synergistic effects of Cu2+andpara-aminobenzoic acid grafted on graphene oxide.

Morpholine derivative oxidation ring-opening method and product thereof

The invention relates to a morpholine derivative oxidation ring-opening method and a product thereof, and belongs to the technical field of compound preparation. The method for promoting oxidative cracking of C (sp3)-C (sp3) bonds of a morpholine derivative by visible light has been successfully developed under the inspiration of the design concept of visible light induced C (sp3)-C (sp3) bond cracking. According to the morpholine derivative oxidation ring-opening method, C (sp3)-C (sp3) bonds without ring stress are cracked by using visible light as an energy source and O2 as a final oxidizing agent, use of transition metal, high temperature, high pressure and chemical equivalent dangerous oxidizing agents is avoided, good functional group tolerance is established, 30 substrates are obtained, the yield is as high as 83%, and a supplementary scheme is provided for realizing oxidative cracking of the morpholine derivative under a mild condition.
