Synthesis of Sulfoximine Carbamates by Rhodium-alyzed

Sulfoximines are of considerable interest for incorporation into medicinal compounds. A convenient synthesis of N-protected sulfoximines is achieved, under mild conditions, by rhodium-alyzed transfer of carbamates to sulfoxides. The first examples of 4-meered thietane-oximines are prepared. Sulfoximines bearing Boc and Cbz groups are stable to further cross coupling reactions, and readily
