'Bis-ornithine' (2,2-bis(aminopropyl)glycine): a new tetravalent template for assembling different functional peptides
Aussedat, Baptiste,Chassaing, Gérard,Lavielle, Solange,Burlina, Fabienne
, p. 3723 - 3726 (2006)
Synthesis of bis-ornithine, a new Cα,α-disubstituted α-amino acid bearing orthogonally protected α and δ amine groups is reported. Bis-ornithine (bisOrn) and dipeptides containing bis-ornithine have been synthesized in solution up to multigram
Copper/GanPhos-Catalyzed 1,3-Dipolar Cycloaddition of Azo?-methine Ylides: An Efficient Access to Chiral Pyrrolidine Spirocycles

supporting information, p. 1331 - 1340 (2020/11/30)
A highly efficient copper/GanPhos-catalyzed 1,3-dipolar cyclo?-addition?-of azomethine ylides is reported. This viable transformation provides a series of optically active spiro[dihydronaphthalene-2,3′-pyrrolidine]s, bearing one spiro quaternary and three tertiary stereogenic centers, in good yields and with high ee values. This protocol features high diastereo- A nd enantioselectivity, broad substrate scope and mild reaction conditions.
Silver/palladium relay catalyzed 1,3-dipole annulation/allylation reactions to access fully substituted allyl imidazolidines
