Reductive Hydroxymethylation of 4‐Heteroarylpyridines
Abstract: The activation of pyridinium salts with electron‐withdrawing heterocycles enables an iridium‐catalyzed reductive hydroxymethylation reaction to proceed smoothly, facilitating the preparation of useful 3D heteroaryl‐substituted functionalized piperidines. The methodology is used to prepare 3‐hydroxymethylated analogues of pharmaceutical agents. Mechanistically, formaldehyde acts as both a hydride donor and the electrophile, leading to the formation of two new carbon–hydrogen bonds and one new carbon–carbon bond under relatively mild conditions.
