N-heterocyclic carbene-catalyzed enantio- and diastereoselective synthesis of tricyclic pyrimidine rings bearing contiguous C–N and C–C stereogenic axes
摘要
An N-heterocyclic carbene (NHC)-catalyzed [3+3] cycloaddition reaction is developed for the enantio- and diastereoselective synthesis of tricyclic pyrimidine rings bearing contiguous C–N and C–C stereogenic axes. The chiral products were obtained in moderate yields and excellent enantio- and diastereoselectivities. Notably, these functionalized molecules exhibit significant potential applications in organic synthesis and bactericide development.
