Homologation of trifluoroacetimidoyl iodides by palladium-catalyzed carbonylation. An approach to α-amino perfluoroalkanoic acids.
摘要:
Homologation of trinuoroacetimidoyl iodides and the related perfluoro-compounds by palladium-catalyst under CO(1atm)-atmosphere in the presence of alcohols gives alpha-imino perfluoroatkanoates which are transformed to alpha-amino perfluoroalkanoic acids.

gold-catalyzed Povarov-type reaction of fluorinated imino esters and furans is described. The process, which takes place in dichoromethane at room temperature, gives rise to novel fluorinated tetrahydrofuran-fused tetrahydroquinolines in good yields and moderate levels of diastereoselectivity in a very simple manner. The reported examples expand the versatility of the Povarov reaction to unprecedented fluorinated

A tandem gold‐catalyzed hydroamination/formal aza‐Diels–Alder reaction is described. This process, which employs quaternary homopropargylaminoester substrates, leads to the formation of an intrincate tetracyclic framework and involves the generation of four bonds and five stereocenters in a highly diastereoselective manner. Theoretical calculations have allowed us to propose a suitable mechanistic

Fluorinated aminoacids are a class of highly valuable building blocks that are widely employed in biological science and pharmaceutical industry for improved stability, activity, and folding property of proteins. However, the synthetic approach has conventionally been constrained by harsh conditions and limited substrate range. We demonstrate a general synthetic protocol for photoinduced α-CF3 amino acids
