2,2-Dimethyl-I,3-dioxolane-4-carboxylic acid derived chiral building blocks were prepared from substituted a&unsaturated acids with high enantiomeric purities by enzymatic hydrolysis of their n.butyl esters.
The relative stereochemistry of the title compound, C~16~H~22~N~4~O~2~, a key intermediate in the synthesis of 3-deoxy imino sugars, was firmly established by X-ray crystallographic analysis. The absolute configuration was inferred from the starting material, D-galactose. There are no unusual crysta
In the title compound, C 22 H 23 Cl 2 N 5 O 3 , the triazole ring is essentially planar. The crystal packing is determined by van der Waals forces and hydrogen bonds, nostacking interactions being observed.
