Bizet, Vincent published the artcileDirect Access to Furoindolines by Palladium-Catalyzed Intermolecular Carboamination, Recommanded Product: 2′-(Dicyclohexylphosphino)-N2,N2,N6,N6-tetramethyl-[1,1′-biphenyl]-2,6-diamine, the publication is ACS Catalysis (2016), 6(10), 7183-7187, database is CAplus.
A versatile Pd-catalyzed intermol. syn-carboamination of dihydrofurans giving access to the ubiquitous furoindoline motif is described. The efficiency of the process relies on the use of Buchwald-type biarylphosphines and the perfect control for site-selectivity of Pd insertion across the C=C bond. A catalytic sequence consisting of Heck and carboamination cross-coupling reactions from readily available dihydrofurans affords-in usually high chem. yields and high levels of diastereocontrol-poly(hetero)cyclic compounds that would be difficult to access by established methods. Encouraging preliminary results for the enantioselective carboamination of 2,3-dihydrofurans are also disclosed.
