Chiral alpha-silylsulfinamides, prepared by the treatment of an alkyldiphenylsilane with lithium followed by its addition to a sulfinimine, can be applied to the synthesis of 1,3-azasilaheterocycles as derivatives of cyclic alkaloids. This synthetic route, which involves intramolecular substitution of an amino alcohol or cyclization of an amino acid promoted by 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC), represents a convenient means for accessing these silicon-containing heterocycles.
