摘要:
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.
摘要:
An enantiomeric mixture of a chiral amino acid is separated into its respective enantiomers through chromatography on a chiral polysaccharide stationary phase eluting with a mobile phase comprising (i) a liquid lower alkanol and (ii) a carboxylic acid soluble in the lower alkanol. The mobile phase may also contain a liquid hydrocarbon.
