α-GalCer analogues featuring a phytoceramide 3- and 4-amino group have been synthesized. A Mitsunobureaction involving phthalimide was employed for the introduction of the amino groups at the 3- and 4-positions of suitable phytosphingosine-derived precursors. The influence of these modifications on the interaction with the T-cell receptor of NKT cells was investigated, as well as the capacity of the
