  The present disclosure provides processes for the preparation of lipid conjugated cyclic carbonate derivatives. More specifically, the present disclosure is based on the finding that reacting lipids, such as, ceramides, with N,N′-disuccinimidyl derivative, resulted in the formation of, isolatable, substituted cyclic [1,3]-dioxan-2-one and [1,3]-dioxan-2-thione compounds. These isolatable cyclic substituted compounds and derivatives thereof may be used for various applications, such as in vaccination.
