A synthetic pathway to new sugar containing tripodal triamines of the TAME type (1,1,1-tris(aminomethyl)ethane) is presented. The tripodal bromo substituted precursors Ac3Xyl-O-CH2C(CH2Br)3, Ac4Glc-O-CH2C(CH2Br)3 and Ac4Gal-O-CH2C(CH2Br)3 (2a-c) were obtained by glycosidation reaction of the fully acetylated glycopyranosides with pentaerythritol tribromide. Nucleophilic substitution to the corresponding
