A tris(bipyridine) ligand 1 with two BINOL (BINOL = 2,2'-dihydroxy-1,1'-binaphthyl) groups has been prepared in two enantiomerically pure forms. This ligand undergoes completely diastereoselective self-assembly into D2-symmeteric double-stranded trinuclear helicates upon coordination to copper(I) and silver(I) ions and to...

Two New Carbaalanes: Compounds with an Al(7)C(5) and a.

Angewandte Chemie (International ed. in English)

Angew Chem Int Ed Engl. 2000 Jan;39(2):406-409.

The hydroalumination of aluminum ethynides leads to the formation of carbaalanes as a new class of compounds, which have clusters exclusively formed by carbon and aluminum atoms. Two novel carbaalanes with Al(7)C(5) and Al(7)C(4) clusters are described-the latter is...

Developmental regulation of H+-ATPase-dependent auxin responses in the diageotropica mutant of tomato (Lycopersicon esculentum).

Rapid auxin effects on H+ pumping across the plasma membrane precede auxin-induced elongation growth of hypocotyls and swelling of guard cells, as well as auxin inhibition of root growth. To investigate whether auxin-signalling mechanisms in such diverse cell types...

Reexamination of the Acid growth theory of auxin action.

Plant Physiol. 1990 Jul;93(3):931-9. doi: 10.1104/pp.93.3.931.

Some crucial arguments against the acid growth theory of auxin action (U Kutschera, P Schopfer [1985] Planta 163: 483-493) have been reinvestigated by simultaneous measurements of proton fluxes and growth of maize (Zea mays L.) coleoptiles. Special care was...

Self-discriminating self-assembly of dinuclear heterochiral rhombs from Tröger's base derived bis(pyridyl) ligands.

Chemistry. 2010 Feb 22;16(8):2418-26. doi: 10.1002/chem.200902993.

Five racemic dissymmetric bis(pyridyl) ligands based on 2,8- or 3,9-difunctionalised Tröger's base derivatives have been synthesised. Only those derived from a 2,8-difunctionalised scaffold were found to undergo selective self-assembly to discrete self-assembled dinuclear metallosupramolecular aggregates of rhomboid shape upon...

An enantiomerically pure BINOL-based bis(3-pyridyl) ligand 1 assembles into a homochiral [Pd4(1)8] complex upon coordination to tetravalent Pd(II) ions. The formation of this aggregate is templated by two tetrafluoroborate counterions that are encapsulated in two peripheral cavities. The resulting...

Beilstein J Org Chem. 2014 Apr 09;10:825-31. doi: 10.3762/bjoc.10.78. eCollection 2014.

Two new 9,9'-spirobifluorene-derived crown ethers were prepared and used to recognise constitutionally isomeric amino acid derivatives. The performance of the receptors was evaluated by ESI-mass spectrometry using the isomer labelled guest method (ILGM). This method revealed the preferred binding...

Planar chiral 5,11-disubstiuted dibenzo[a,e]cyclo-octatetraenes (dbCOTs) have been developed as the first useful chiral homologs to dbCOT-ligands for asymmetric applications. Methods enabling the preparation of such compounds on a gram-scale in enantiomerically pure form are described. Evaluated as ligands in...
