Maeda, Yoshiaki published the artcilePractical Asymmetric Synthesis of Chiral Sulfoximines via Sulfur-Selective Alkylation, Safety of 1-Iodohexane, the publication is Journal of Organic Chemistry, database is CAplus and MEDLINE.
Herein, an asym. synthesis of chiral sulfoximines RS(=NPiv)(O)C(CH3)3 (R = Me, i-Bu, 4-(1,3-dioxolan-2-yl)butyl, etc.) through a stereospecific S-alkylation of readily accessible 2,2-dimethyl-N-[(S)-2-methylpropane-2-sulfinyl]propanamide under practical conditions was demonstrated. A key to establishing the practical conditions was the identification of the intermediate structure in the previously reported S-alkylation by X-ray crystallog. anal.
