An enantioselective synthesis of 2-alkyl-3-phenyltropanes by an asymmetric 1,3-dipolar cycloaddition reaction

Abstract
A method for gaining access to 2-alkyl-3-phenyl-substituted tropanes using the chiral dipolarophile (R)-p-tolyl vinyl sulfoxide in the asymmetric 1,3-dipolar cycloaddition reaction with the oxidopyridinium betaine 4 is described.
