Abstract

A series of enantiomerically pure selenonium salts 2 were prepared, using 2-exo-hydroxy-10-bornyl group as a chiral ligand, in good yield and selectivity by the reaction of chiral halooxaselenuranes 1 with Grignard reagents. A sharp pyramidal structure with RSe absolute configuration at the selenium atom was confirmed by an X-ray analysis of 2b. The stereochemical outcome turned out to be different with that of the telluronium salts.
