Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Organic Letters called Expedient Synthesis of α-Heteroaryl Piperidines Using a Pd-Catalyzed Suzuki Cross-Coupling-Reduction Sequence, Author is Hesp, Kevin D.; Fernando, Dilinie P.; Jiao, Wenhua; Londregan, Allyn T., which mentions a compound: 98006-90-7, SMILESS is CC1=CN=C(Br)C=N1, Molecular C5H5BrN2, Product Details of 98006-90-7.
A method for the modular synthesis of α-heteroaryl piperidines is reported. The two-step procedure consists of an initial Pd-catalyzed Suzuki cross-coupling of the heteroaryl bromide with a boronate ester derived from N-Boc-piperidone, followed by subsequent tetrahydropyridine reduction Using this method, α-heteroaryl piperidine products featuring a broad range of pharmaceutically relevant azine and diazine substitutions have been prepared
