Nucleophilic Aromatic Substitution Reactions of 1-Methoxy-2-(diphenylphosphinyl)naphthalene withC-,N-, andO-Nucleophiles: Facile Synthesis of Diphenyl(1-substituted-2-naphthyl)phosphines
We synthesized a series of phosphine–olefin-type chiral aminophosphines, and we confirmed that these each exists as two rotamers at the C(aryl)–N(amine) bond. We also investigated the ability of these aminophosphines to act as chiralligands for Pd-catalyzed asymmetricallylicsubstitutionreactions, such as the alkylation of allylic acetates with malonates or indoles, and we found they gave high
