Expedient Synthesis of α-Heteroaryl Piperidines Using a Pd-Catalyzed Suzuki Cross-Coupling–Reduction Sequence
摘要:
A method for the modular synthesis of alpha-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, alpha-heteroaryl piperidine products featuring a broad range of pharmaceutically relevant azine and diazine substitutions have been prepared.

The late-stage introduction of diverse heterocycles onto complex small molecules enables efficient access to new medicinally relevant compounds. An attractive approach to such a transformation would utilize the ubiquitous aliphatic C–H bonds of a complexsubstrate. Herein, we report a system that enables direct C–H heteroarylation using a stable, commercially available O-alkenylhydroxamate with heterocyclic
