Reported herein is a straightforward and enantiodivergent synthesis of both enantiomers of trifluoromethylatedanalogues of calcimimeticNPS R-569 in a highly estereoselective manner. The synthesis features a diastereoselective synthesis of the N-(isopropylsulfinyl)imine unit by the "DAG methodology" and a diastereoselective addition of Ruppert-Prakash's reagent to the imine as the key steps.
