sulfur−alkene hybrid ligand has proven to be highly effective for rhodium-catalyzed formal cycloaddition reactions of racemic butadiene monoxide and imines to furnish spirooxindole oxazolidines or 1,3-oxazolidines with high yields and stereoselectivities. A possible dynamickineticresolution as well as a kineticresolution is considered to be involved in this catalytic process.
