  • Title: Rhodium(III)-catalyzed intramolecular redox-neutral annulation of tethered alkynes: formal total synthesis of (±)-goniomitine.
    Author: Zhou B, Du J, Yang Y, Li Y.
    Journal: Chemistry; 2014 Sep 26; 20(40):12768-72. PubMed ID: 25145612.
    Abstract:
    A Rh(III)-catalyzed intramolecular redox-neutral atom-economic annulation of a tethered alkyne has been developed to efficiently construct 2-amidealkyl indoles with completely reversed regioselectivity by a C-H activation pathway. Furthermore, using the Rh(III)-catalyzed C-H activation/annulation as a key step, a one-pot synthesis of pyrido[1,2-a]indoles has also been developed and applied to a highly efficient formal total synthesis of (±)-goniomitine.
