The use of a bifunctional Cinchona alkaloid catalyst has provided a new organocatalytic strategy for the enantioselective addition of diphenylphosphine to a range of nitroalkenes, affording optically active beta-nitrophosphines (up to 99% ee after crystallization); this organocatalytic approach, providing a direct route to a new class of potentially useful enantiopure P,N-ligands, constitutes a...

Ferroquine (FQ, SSR97193) is currently the most advanced organo-metallic drug candidate and about to complete phase II clinical trials as a treatment for uncomplicated malaria. This ferrocene-containing compound is active against both chloroquine-susceptible and chloroquine-resistant Plasmodium falciparum and P. vivax strains and/or isolates. This article focuses on the discovery of FQ, its ant...

Most drugs used today are purely organic compounds. Especially after the enormous success of the cisplatin (Fig 1) in tumor treatment, interest in metal complexes has grown (Allardyce & Dyson, 2006). Synthetic organometallic compounds are generally considered to be toxic or non-compatible with biological systems. Despite this perception, the medicinal properties of organometallic compounds, in ...

The Sn(IV) atom in the title compound, 2[Sn(CH(3))(2)(C(6)H(5))Cl(H(2)O)]·C(10)H(20)O(5), exists in a trans-C(3)SnClO trigonal bipyramidal geometry in which the organo substituents occupy the equatorial sites. The coordinated water mol-ecule forms two hydrogen bonds to the 15-crown-5 mol-ecule, which is disordered about a center of inversion.

A series of bimetallic organo-group 4 "constrained geometry" catalysts and binuclear bisborane and bisborate cocatalysts have been synthesized to probe catalyst center-catalyst center cooperativity effects on olefin enchainment in homogenous olefin polymerization and copolymerization processes. Significant nuclearity effects are found versus mononuclear controls, and the effect can be correlate...
