The synthesis of improved optically active selenium compounds for electrophilic additions to C=C double bonds is described. These reagents allow the formation of methoxyselenenylated products with high diastereoselectivities (up to 93% de). Intramolecular aminoselenenylations with chiral selenium electrophiles provide a short route to tetrahydroisoquinoline alkaloids.
