  • General Description (R)-(+)-2-Methyl-2-propanesulfinamide, also known as (R)-tert-butanesulfinamide, is a valuable chiral auxiliary widely used in asymmetric synthesis. It is efficiently synthesized via catalytic asymmetric oxidation of di-tert-butyl disulfide using a cost-effective chiral Schiff base ligand and H2O2 as the oxidant, yielding the intermediate tert-butyl tert-butanethiosulfinate with high enantioselectivity (91% ee). Subsequent nucleophilic displacement with LiNH2 provides the sulfinamide in high yield (91%), which can be further purified to enantiomeric purity by recrystallization. This scalable method enables large-scale production, making (R)-(+)-2-Methyl-2-propanesulfinamide a practical reagent for stereoselective transformations, including the synthesis of sulfoxides, sulfinamides, and sulfinimines.
