inhibitory profile was observed for several compounds, which was comparable, if not superior, to that of 2. A promising cytotoxic activity was found for selected macrocycles against lung and colon cancer cell lines. Further elaboration of selected candidates led to compounds with an improvedselectivity against HDAC6 over the other isozymes. Pair-fitting analysis was used to compare one of the best

A copper-catalyzed radical carbochlorination or carbobromination is reported. Intramolecular cyclization occurred through aryl radicals generated in situ from bench-stable aryl amines with aqueous hydrogen halides as the halogen sources. A variety of (3-halomethyl)-1,2-dihydrobenzofuran derivatives were prepared in up to 92% yield through this one-pot protocol utilizing widely available starting materials
