Intramolecular Michael-Type Additions to Vinyl Bissulfoxides: Enantioselective Synthesis of Chiral Aldehydes
The diastereoselective auxiliary-based intramolecular Michael-type additions to alkylidene bissulfoxides derived from dithiane and dithiolane were investigated. Utilization of substrates bearing N- and O-nucleophilic functions led to the formation of the respective cyclic substrates with selectivities ranging from 51:49 to 85:15. Cleavage of the bissulfoxide moiety by a two-step sequence yielded chiral
