An enantioselective C-H iodination reaction using a mono-N-benzoyl- protected amino acid has been developed for the synthesis of chiral diarylmethylamines. The reaction uses iodine as the sole oxidant and proceeds at ambient temperature and under air.

A new Bronsted acid-assisted chiral Bronsted (chiral BBA) acid catalyst (1) was developed by substituting a hydroxy group of optically active 1,1′-bi(2-naphthol) with a stronger Bronsted acidic group such as a bis(trifluoromethanesulfonyl)methyl group. The enantioselective Mannich-type reaction of ketene silyl acetals with aldimines catalyzed by (R)-1 in the presence of stoichiometric achiral proton sources gave (S)-β-amino esters in high yield with moderate to good enantiomeric excesses.
