: Enantiopure 2,6-disubstitutedmorpholines have been synthesized through the ring opening of chiral, nonracemic oxiranes with nitrogen nucleophiles, under solid-liquid phase-transfer catalysis (SL-PTC) conditions. The β-hydroxytosyi amides resulting from the ring opening of a first epoxide with TsNH 2 was used as nucleophile, after protection of the hydroxyl group, in the reaction with a second oxirane
