We report a redox-neutral P(O)-N coupling reaction of P(O)-H compounds with azides via photoredox and copper catalysis, providing new access to useful phosphinamides, phosphonamides, and phosphoramides. This transformation tolerates a wide range of nucleophilic functionalities including alcohol and amine nucleophiles, which makes up for the deficiency of classical nitrogen nucleophilic substitution reactions. As a demonstration of the broad potential applications of this new methodology, late-stage functionalization of a diverse array of azido-bearing natural products and drug molecules, a preliminary asymmetric reaction, and a continuous visible-light photoflow process have been developed.

A novel approach to 2-azabicyclo[2.2.1]heptane-1-carboxylic acid (2,4-ethanoproline) is reported starting from (2S,4R)-4-hydroxyproline. The synthetic scheme consists of 10 steps and results in 22% total yield of the title compound. Enantiomeric purity of the product is checked by chiral stationary phase HPLC.
