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 α‐alkylated unnatural α‐amino acids. It merits mentioning that the mild conditions and the good functional‐group tolerance allow the modification
An efficient asymmetric aerobic oxidation of tetrahydroisoquinolines with terminal alkynes was realized under mild reaction conditions using O2 as the sole oxidant. A chiral N,N′-dioxide/zinc(II)/iron(II) bimetallic cooperative catalytic system proves to be efficient for the formation of various α-alkynyl substituted tetrahydroisoquinolines in good to excellent yields and enantioselectivities. A primary

An organocatalysis/copper-catalyzed asymmetric oxidative sp(3) C-H olefination reaction of tertiary amines with olefins usingmolecularoxygen as the sole oxidant under mild conditions was realized for the first time. This novel strategy provides an efficient and environmentally friendly way to access diversify optically active C(1)-alkene tetrahydroisoquinoline derivatives.
