A convenient synthesis of indoloquinolinones via 3-arylation of Indole-2-carboxamide (cas 1670-84-4)s and PIDA-mediated C–N bond formation

Add time:09/27/2019    Source:sciencedirect.com

A series of substituted indoloquinolinones were readily synthesized, via two steps, from indole-2-carboxylic acid and its derivatives: a 3-arylation of indole-2-carboxamides and a subsequent PIDA-mediated oxidative C–N bond formation. The underpinning strategy involves a Cu(I)-promoted C(sp2)–C(sp2) coupling and a PIDA-mediated oxidative C(sp2)–N coupling.
