The idopyranose ring plays a pivotal role in the conformational, dynamical, and intermolecular binding aspects of glycosaminoglycans like heparin and dermatan sulfate and it was early on assigned a role in the Sugar Code governing biological recognit

Publikováno v: Acta Crystallographica Section E, Vol 64, Iss 1, Pp o337-o337 (2008)

In the chiral title compound, C18H28O3, the two six-membered rings of the perhydronaphthalenone adopt a rigid chair–chair conformation and the five-membered dioxolanyl ring adopts an envelope conformation. The crystal structure is stabilized only b

We present a straightforward protocol for making (phosphanyl-carbene)PdII complexes. These complexes have bidentate ligands containing an acyclic diamino- or aminooxy-carbene and a phosphane. The synthesis gives good yields (typically 70-90 %) for a

A new Au(III) coordination compound with the ligand 2-(phenylazo)pyridine has been synthesized and fully characterized by means of elemental analysis, IR, UV–visible, conductivity measurements, NMR, electrospray ionization (ESI-MS) and inductively

Publikováno v: Macromolecular Rapid Communications, 28(17), 1809-1815. Wiley-VCH Verlag

A series of chiral thio- and oxo-substituted polythiophenes and polythienylethynylenes has been synthesised and investigated. The replacement of an oxo-linkage by a thio-linkage distorts and/or inhibits the helical aggregation behaviour. The quenchin
