| Abstract |
Facile gold-catalyzed heterocyclization based upon intermolecular trapping of the generated alpha-oxo gold carbenes with various cyanamides (RRNCN)-R-2-N-3 (R-2/R-3 = Alk/Alk, -(CH2)(2)O(CH2)(2)-, Ar/Ar, Ar/H) has been developed. In most cases, 2-amino-1,3-oxazoles fiinctionalized at the nitrogen atom as well as at the fifth position of the heterocyclic ring (12 examples) were isolated hi good to moderate yields. |
