(Table3). Initially, acyclic tertiary alkyl bromides were examined. We were pleased to find that tertiary alkyl centers containing primary alkyl bromides, aryl, esters and ketone functional groups were compatible with the reaction conditions and afforded their corresponding products (5a–5k) in good...
This invention relates to a process for producing N-aryl-2-lactams and N-cycloalkyl-2-lactams by reductive amination of lactones with aryl amines utilizing a metal catalyst, which is optionally supported. LE Manzer - US 被引量: 2发表: 2004年 Reductive Amination of Aldehyde and Ketone with Am...
Here, we show a deacylative annulation strategy for preparing a large variety of aromatic-fused rings from linear simple ketone precursors. The reaction starts with homolytic cleavage of the ketone α C–C bond via a pre-aromatic intermediate, followed by a radical-mediated dehydrogenative ...
