Two oxathiozolidine‐S‐oxide templates have been developed and used in a four‐component coupling protocol for the synthesis of a wide range of chiralsulfinimines in high enantiomeric excesses. The templates can be synthesized from cheap commodity chemicals in three steps in high yields. Furthermore the template is easily recovered in high yields for recycling.
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.
