A method for the synthesis of difficult-to-access amides was developed through the coupling of stericallyhindered carboxylic acids and electron deficient amines via SO2F2-mediated dehydration. The method feathers with broad substrate scope, mild conditions, excellent functional group compatibility and high yields.

Methods utilizing continuous flow photochemistry, an enabling synthetic technology, have been developed for the generation of phenanthridinones via an intramolecular photochemical cyclization of 2-chlorobenzamides for the purposes of generating poly(ADP-ribose) polymerase inhibitors. Herein we report 16 examples of a single-step flow photocyclization which produces substituted phenanthridinones in
