摘要
An Iridium-catalyzed [4+3] cyclization of ortho-tosylaminophenyl-substituted para-quinone methides with vinylic oxiranes or vinyl aziridines has been successfully developed. In the presence of [Ir(cod)Cl](2) and a suitable base, this unprecedented cascade reaction occurs readily in good yield (up to 97%) and high diastereoselectivity (dr>20 : 1), providing a highly efficient synthetic approach to synthetically valuable seven-membered heterocyclic frameworks.
