Application of polymer-bound phosphonium salts as traceless supports for solid phase synthesis
Hughes, Ian

The utility of the phosphonium group as a traceless linker for the solid phase synthesis of small organic molecules is demonstrated by the elaboration of polymer-bound phosphonium salts and their subsequent cleavage to alkyl, alkenyl and heteroaryl produc

The copper-catalyzed enantioselective C-H arylation between 2-arylindoles and hypervalent iodine reagents has been successfully developed, which provides a convenient and economical route to the highly atroposelective synthesis of axially chiral indole de

Abstract: A regioselective C2 arylation of indoles, benzothiophene and benzofuran without directing group has been accomplished using economically cheap Pd NPs and NHC-Pd@MNPs catalyst. The reusable catalyst is efficiently employed to access C2 arylated heterocycles in good to excellent yield. The reusability of the catalyst is studied up to five cycles and a gram-scale synthesis has been achieved. The reaction mechanism is well supported by control experiments and literature precedents.
