Crystal structure of N-(1-benzyl-2-oxoindolin-3-yl)-N-p-tolylbenzofuran- 2-carboxamide, C31H24N2O3

The crystal structure of 5-(benzofuran-2-carbonyl)-N-cyclohexyl-5,6-dihydrophenanthridine-6-carboxamide, C29H26N2O3

“…Dihydrophenanthridines are prevalent structural units in many natural products and biologically active molecules [6], and their syntheses have attracted much attention [7,8]. As a continuation of our work on post cyclization of the Ugi/Rap-Stoermer reaction product [5,9], here a novel dihydrophenanthridine was designed and synthesized. Similar to the related dihydrophenanthridine [10], the titled compound substituted with benzofuran-2-carbonyl moiety was synthesized via a Pdcatalyzed intramolecular direct arylation [11].…”
