Photocyclization of N,N-phthaloylanthranilic amides coupled to ω-amino acids with increasing chain lengths

Medium-sized heterocyclic ring systems are available via a photo-elctron transfer (PET)-induced decarboxylation–cyclization sequence using a triad composed of electronically excited acceptor, linker and electron donor A*–L–D with target ring sizes varying from 8–16.
