摘要
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.
