ligands required the preparation of chiral fluoroalkyl benzilicacids. An enantioselective synthesis of substitutedbenzilicacids was achieved using 8-phenylmenthol as the chiral auxiliary. Grignard addition to the si face of 8-phenylmenthyl benzoylformate 7 proceeded with high selectivity. The results of the chiral induction support assignments of the chirality of benzilicacids previously resolved
