A palladium-mediated domino reaction was developed to conveniently synthesize phenanthridinone derivatives. Phosphine ligand 1 strongly promotes the domino process, which includes aryl-aryl coupling and C-N bond formations concomitant with a deamidation reaction. The versatility and applicability to a broad range of substrates make this reaction useful for the development of bioactive derivatives. [reaction: see text].
Enantioselective mono‐fluorination of α‐keto esters was achieved using a mildly basic palladium μ‐hydroxo complex as catalyst. Subsequent one‐pot reduction afforded optically active β‐fluoro‐α‐hydroxy esters. These compounds were then converted into β‐fluoro‐α‐amino esters, which are potentially useful in medicinal chemistry research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
