Enantio-and diastereo-selective conjugate addition of glycine derivatives to α,β-unsaturated imines generated in situ from sulfonylindoles under phase transfer catalysis was described. The corresponding syn β-substituted tryptophan derivatives were obtained in up to 99% yield with up to 95% ee and 5:1 dr.

Key words: phase transfer catalysis, glycine derivative, sulfonylindoles, β-substituted tryptophans
