Gold(I)-Catalyzed Intramolecular Dihydroamination of Allenes with N,N′-Disubstituted Ureas to Form Bicyclic Imidazolidin-2-ones
[Image: see text] Reaction of N-δ-allenyl urea 1 with a catalytic 1:1 mixture of gold(I) N-heterocyclic carbene complex (5)AuCl [5 = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidine] and AgPF(6) at room temperature for 2 h led to isolation of bicyclic imidazolidin-2-one 4 in 93% yield as a single di...
