α-Galactosyl-ceramide (1) has been identified as a powerful modulator of immunological processes through its capacity to bind CD1d molecules and specifically activate invariant natural killer (NK)-like T cells (iNKT cells). This paper describes the synthesis of 1, the analogous α-galactosyl-ceramide 3, and its short chain analogue ‘OCH’ (2), by use of the 4,6-di-O-tert-butylsilylene (DTBS) protecting group to produce a powerful α-galactosylating agent. In vivo experiments confirmed these compounds to be potent and selective activators of iNKT cells in a CD1d-dependent manner, each inducing a unique profile of cytokine release. This synthesis strategy will permit the generation of novel derivatives for use in the study of the mechanism of iNKT cell activation.
