Electric Literature of 161265-03-8. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 161265-03-8, Name is (9,9-Dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine)
Visible-Light-Driven, Copper-Catalyzed Decarboxylative C(sp3)?H Alkylation of Glycine and Peptides
Despite a well-developed and growing body of work in Cu catalysis, the potential of Cu to serve as a photocatalyst remains underexplored. Reported herein is the first example of visible-light-induced Cu-catalyzed decarboxylative C(sp3)?H alkylation of glycine for preparing alpha-alkylated unnatural alpha-amino acids. It merits mentioning that the mild conditions and the good functional-group tolerance allow the modification of peptides using this method. The mechanistic studies revealed that a radical?radical coupling pathway is involved in the reaction.
