Synthesis of Bicyclic Guanidines via Cascade Hydroamination/Michael Additions of Mono-N-acryloylpropargylguanidines
摘要:
A cascade silver(I)-catalyzed hydroamination/Michael addition sequence has been developed to deliver highly substituted bicyclic guanidines. This transformation gives rise to geometrically and constitutionally stable ene-guanidines and generates a remote stereocenter with moderate to high diastereoselectivity.
