- L -arabinitol-based functional polyurethanes
-
Three new polymerizable diols, based on mono-, di-, and tri-O-allyl-L-arabinitol derivatives, were prepared from L-arabinitol as versatile materials for the preparation of tailor-made polyurethanes with varied degrees of functionalization. Their allyl fun

- One-pot cascade synthesis of azabicycles via the nitro-Mannich reaction and N -alkylation
-
A one-pot, metal-free process for the synthesis of azabicycles is developed. The key transformations involved a cascade of double intramolecular cyclizations via the nitro-Mannich reaction and N-alkylation, providing various ring systems of azabicycles in

- Improved stereochemical analysis of conformationally flexible diamines by binding to a bisporphyrin molecular clip
-
The relative stereochemistry of acyclic diamines with several stereogenic centers has been analyzed by NMR spectroscopy in combination with conformational deconvolution. Binding to a bisporphyrin molecular clip improves the stereochemical assignment signi

- Synthesis of cyclitols fused with a furoxan ring from alditols by intramolecular nitrile oxide dimerization
-
The synthesis of cyclitols fused with a furoxan ring has been achieved by conversion of an alditol to a bis-(aldoxime) and further oxidation of the oxime groups with N-chlorosuccinimide to nitrile oxides, which spontaneously dimerize intramolecularly to form a furoxan ring.
