Abstract
A new immunostimulant, the 4'-epimer of α-C-GalCer, was synthesized from a C2-symmetric dienediol and α-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 α-C-GalCer.

Abstract
The syntheses of 12 stereochemically diverse polyhydroxyl aminocyclohexane ("aminocyclitols") derivatives are described. These short syntheses require 2-5 steps from N-(2,4-cyclohexadien-1-yl)phthalimide, which is prepared in two steps from tricarbonyl(cyclohexadienyl)iron(1+). The relative stereochemistries of the aminocyclitols were assigned by (1)H NMR spectroscopy as well as X-ray diffraction analysis.
