A novelbifunctionalchiralthioureaorganocatalyst bearing a glycosyl scaffold and a tertiary amino group was synthesized starting from readily available alpha-D-glucose. This thiourea was proven to be an effective organocatalyst for the asymmetric aza-Henry reaction between N-Boc imines and nitromethane. The corresponding adducts were obtained in good to excellent yields with excellent enantioselectivities
