Novel chiral aminoacidderivedionicliquid crystals with amine and amide moieties as spacers between the imidazolium head group and the alkyl chain were synthesised. The key step in the synthesis utilised the relatively uncommon SO3 leaving group in a microwave‐assisted reaction. The mesomorphic properties of the mesogens were determined by differential scanning calorimetry (DSC), polarising optical
Using Pd(CF3CO2)(2)/(SS)-f-binaphane as the catalyst, an efficient enantioselective synthesis of cyclic sulfamidates was developed via asymmetric hydrogenation of the corresponding cyclic imines in 2,2,2-trifluoroethanol at room temperature with high enantioselectivities (up to 99% ee).

BOC- and dibenzosuberyl-protected chiral and hindered cyclic sulfamidates ([1,2,3]-oxathiazolidine-2,2-dioxides) were synthesized and subsequently deprotected using trifluoroacetic acid. The resulting crystalline sulfamidates were then used in several alkylation reactions involving benzyl bromide and alcohols in a versatile route to cyclic sulfamidates with differing N-alkyl substituents.
