To gain insight into the biol. properties of tetramic acid lactam cylindramide 1, the analogs 4a-d bearing a cyclopentane ring instead of the pentalene unit were prepd. by tandem conjugate addn./enolate trapping of cyclopentenone 10; a Sonogashira or Still ...
A review; an overview of recent developments from the Lab. of Organometallic and Medicinal Chem. at the EPFL in biphasic catalysis, involving aq. solns. and ionic liqs., and in CO2 redn. is presented. Progress in the use of ionic liqs., either by catalyst ...
Immunofluorescence assays indicate that anguinomycin C is a potent inhibitor of protein export from the nucleus. Key features in the total synthesis of this antitumor natural product include a Cr-catalyzed enantioselective hetero-Diels– Alder reaction, a N ...
The biphasic hydrosilylation of 1-hexadecene with siloxane B9800 in a range of ionic liqs. is reported. Of the ionic liqs. tested, [C4py][BF4] and [C4-3-pic][BF4] offer the optimum compromise between activity and ...
Synergic effect of iron and copper salts as catalysts for the Sonogashira–Hagihara cross-couplings of aryl iodides with terminal alkynes is demonstrated. High yields of cross- coupled products are obtained under conditions that are smoother than those usin ...
Palladium(II) complexes with N,N-bis(diphenylphosphino)aniline ligands catalyze the Heck reaction between styrene and aryl bromides, affording stilbenes in good yield. The structures of two of the complexes used as pre-catalysts have been detd. by single-c ...
A divergent and regiocontrolled Pd-catalyzed domino sequence involving an intramol. N-arylation and an intermol. Heck reaction has been developed, providing rapid access to functionalized benzodiazepine-2,5-diones, e.g. I. The starting materials were synth ...
Room temperature ionic liquids (RTILs), considered as "designers' solvents", are attracting a great attention because of their possibility to be tailored based on property requirements. The ionic liquids designed and synthesized for carrying out specified ...
Various methods for the synthesis of bimetallic complexes, in which two different metal fragments which are connected by two or three halogeno bridges, are reported. The reactions are usually fast and give rise to structurally defined products in quantitat ...
A series of nitrile-functionalized imidazolium salts (many of which are liquid at room temperature) have been prepared. The reactivity of these salts with PdCl2 has been studied, resulting in salts containing a tetrachloropalladate dianion or co ...
