A simple, general, and practical technology to prepare enantiopure 1,2,3-oxathiazolidine-2-oxide derivatives using chiral aryl N-sulfonyl aminoalcohol derivatives and thionyl chloride is reported. The versatility of these novel chiral building blocks (MIOO and TMPOO), was exemplified by the expedient production of a variety of unique chiral sulfoxides and valuable chiral sulfinamides in excellent yields
This invention encompasses novel methods of preparing sulfinamides and sulfoxides, particularly stereomerically pure sulfinamides and sulfoxides. The invention further encompasses novel compounds from which sulfinamides and sulfoxides can be prepared.
