Published in 2018 at "Tetrahedron Letters"

DOI: 10.1016/j.tetlet.2018.06.008

Abstract: Abstract A C2-symmetric, chiral bis-cyclosulfinamide-olefin ligand composed of two 1-oxo-2,3-dihydro-1,2-benzisothiazole moieties with rigid skeletons and a conformationally flexible butenylene chain is disclosed for the first time. HRMS and 1H NMR analyses verify that the in… read more here.

DOI: 10.1021/acs.organomet.8b00524

Abstract: A series of axially chiral bis-1,2,3-triazol-5-ylidene Au(I) complexes (R)-8a–g and one mono-1,2,3-triazol-5-ylidene Au(I) complex (R)-9a were prepared from commercially available (R)-binaphthyl-2,2-diamine (BINAM) compound, in which, transmetalation of bis(MIC)-bis[Ag(I)] intermediates to the corresponding Au(I) complexes were… read more here.

Published in 2022 at "Journal of the American Chemical Society"

DOI: 10.1021/jacs.1c11857

Abstract: Herein we report the first chiral Au10 nanoclusters stabilized by chiral bis N-heterocyclic carbene (bisNHC) ligands. ESI-MS and single-crystal X-ray crystallography confirmed the molecular formula to be [Au10(bisNHC)4Br2](O2CCF3)2. The chiral Au10 nanocluster adopts a linear… read more here.

Published in 2017 at "Chemical communications"

DOI: 10.1039/c7cc03307a

Abstract: The first highly enantioselective reaction of α,α-dithioacetonitriles with imines has been developed. Good yields and enantioselectivity were observed for the reaction of various imines using chiral bis(imidazoline) catalysts. The obtained products can be converted into… read more here.

Published in 2021 at "New Journal of Chemistry"

DOI: 10.1039/d1nj03248h

Abstract: Conformational chirality is a feature that may arise from the presence of a hindered rotation around a single bond that corresponds to a stereogenic axis. read more here.

Published in 2022 at "Molecules"

DOI: 10.3390/molecules27206926

Abstract: Chiral bis(TTF) diamides have been obtained in good yields (54–74%) from 1,2-cyclohexane-diamine and the corresponding TTF acyl chlorides. The (R,R)-1 and (S,S)-1 enantiomers have been characterized by circular dichroism and the racemic form by single-crystal… read more here.
