A zinc-catalyzed C-H alkenylation of quinoline N-oxides with ynones has been developed to rapidly assemble a broad collection of valuable quinoline-enol organic architectures. Uncommonly, this novel reaction involves C-H functionalization, and N-O, C-C and CC bond cleavage in one operation, and leads exclusively to the formation of an enol rather than a keto product. Application of the enols generated was highlighted by further derivative transformation and preparation of a series of BODIPY analogues with high quantum yields (up to 86%). This journal is

Photocyclization of the internally hidrogen-bonded dibenzoylmethane 2-bromo- and 2-iodo-anils proceed cleanly, though with low quantum yield, to afford a phenanthridine derivative directly and with very little competition from hydrogen abstraction reactio

The tautomers (1, X = Cl, Br, or I) of anils photocyclise to the phenanthridine derivative (2) with varying efficiencies depending on the halogen and the solvent; owing to the low energies of the first excited states the quantum yields vary with irradiation wavelength.
