摘要：

A new immunostimulant, the 4'-epimer of alpha-C-GalCer, was synthesized from a C-2-syminetric dienediol arid alpha-C-allyl galactoside. The intramolecular aziridination and the following reductive ring opening provided the core of the aliphatic amino alcohol with excellent regio- and stereocontrol. The new immunostimulants 3d and 3e gave a better polarized Th1-type cytokine response in murine NKT cells than the benchmarked alpha-C-GalCer.
