An effective and facile method for highly diastereoselective synthesis of quaternary alpha-trifluoromethyl alpha-amino acids was developed in good yields with high diastereoselectivity (dr >20:1) via MgCl2-accelerated addition of benzylzinc reagents (Knochel type organozinc reagents) to (R)-phenylglycinol methyl ether based imines of trifluoropyruvate.
