The Bingel addn. of a trimalonate derived from a chiral, cyclotriveratrylene (CTV)-based tripodal tether to C60 was reinvestigated. The present use of enantiomerically pure (P)- and (M)-configured CTV units in the tether allowed the isolation of a total of ...
Organometallic ruthenium(II) arene complexes containing the PTA ligand ([Ru(eta(6)-arene)Cl-2(PTA)], PTA = 1,3,5-triaza-7-phosphatricyclo-[3.3.1.1] decane, termed RAPTA) show pharmacologically relevant antitumour properties in vitro. Two new enantiomeric p ...
The diastereoselective synthesis of chiral coordination compounds with d metals proved the effectiveness of the pinene-bipyridine approach in predetermining the chirality at the metal centre. The strong Lewis acidic character of lanthanide cations required ...
Chiral esters and amides (I) of pyrrolidine-2-carboxylic acid are new. - Chiral esters and amides of pyrrolidine-2-carboxylic acid, having formula (I), are new. - A = groups F1 or F2; - R' and R'' = 1-20C hydrocarbyl, i.e. acyclic, linear or branched, satu ...
In this thesis, the use of nanotemplates for steering the molecular self-organization at metallic surfaces is investigated. Nanotemplates are surfaces that exhibit a periodic variation of the adhesion energy on the nanometer scale. Preferential adsorption ...
New enantiomerically pure alleno-acetylenic macrocycles were prepd. by oxidative homocoupling of optically active 1,3-diethynylallenes. Enantiomer sepn. resulted from a combined strategy of synthesis and chiral HPLC techniques. Two other achiral stereoisom ...
We report on a simple method for enhancing the efficiency of photoluminescence (PL) emission from selected chiral forms of semiconducting single-wall carbon nanotubes (SWCNTs). The method is based on the use of a fluorescent dye (Nile blue A) that shows th ...
By addn. of an enantiomerically pure nitrile oxide to C70, four chiral isoxazolo[70]fullerene isomers were prepd. and isolated in pure state: two constitutional isomers resulting from addn. to one of the bonds radiating from the polar pentagons, and a cons ...
1-Alkoxy-2-methyl-3-acyloxy-(E,E)-penta-1,3-dienes have been prepared applying among others a modified Danishefsky's general method, including chiral, racemic, and achiral derivatives. ...
A diastereoselective three-component synthesis of chiral 2-(1,2-diaminoalkyl)phenols from an electron-rich phenol, an amine, and a chiral alpha -N,N-dibenzylamino aldehyde is developed. The diastereoselectivity of this phenolic Mannich reaction is temp.-de ...
