Complexation properties of dimeric rhodium(II) tetracarboxylates have been utilised in chemistry, spectroscopy and organic synthesis. Particularly, the combination of these rhodium salts with multifunctional ligands results in the formation of coordination polymers, and these are of interest because of...

We describe the modular synthesis and characterization of several substituted N-hetero benzenacyclooctaphanes (BAOs), a new motif for heteroaromatic conjugated macrocycles. The targets were synthesized via condensation of substituted aromatic ortho-diamines with a cyclic octaketone building block in moderate to...

J Org Chem. 2015 Aug 21;80(16):7876-83. doi: 10.1021/acs.joc.5b00582. Epub 2015 Aug 03.

Unusual regio- and chemoselective oxidation of aromatic amines hindered with ortho substituents (except -NH2, -NHCH3, and -OH) to the corresponding nitro compounds is described by use of nonanebis(peroxoic acid). The mechanistic investigation for selective oxidation of amines ortho-substituted with...

The First Modular Route to Core-Chiral Bispidine Ligands and Their Application in Enantioselective Copper(II)-Catalyzed Henry Reactions.

Chemistry. 2015 Aug 24;21(35):12488-500. doi: 10.1002/chem.201502090. Epub 2015 Jul 31.

The first modular and flexible synthesis of core-chiral bispidines was achieved by using an "inside-out" strategy. The key intermediate, a NBoc-activated bispidine lactam, was constructed in enantiomerically pure form from a chirally modified β-amino acid and 2-(acetoxymethyl)acrylonitrile in just...
