title: Catalytic asymmetric protonation of alpha-amino acid-derived ketene disilyl acetals using P-spiro diaminodioxaphosphonium barfates as chiral proton.
abstract: Chiral diaminodioxaphosphonium salts have been developed and their unique abilities as a chiral proton have been revealed through the establishment of a highly enantioselective protonation of alpha-amino acid-derived ketene disilyl acetals.
