Potassium trimethylsilanolate induced cleavage of 1,3-oxazolidin-2- and 5-ones, and application to the synthesis of (R)-salmeterol.

A convenient and efficient method for the cleavage of 1,3-oxazolidin-5-ones and 1,3-oxazolidin-2-ones utilising potassium trimethylsilanolate in tetrahydrofuran is described. The benzyloxycarbonyl-protecting group is readily removed under the reaction conditions, whereas the N-benzoyl group is stable. A synthesis of (R)-salmeterol exploiting the 2-oxazolidinone ring as a protecting group for the ethanolamine moiety is also described.

Aminoazabenzimidazoles, a Novel Class of Orally Active Antimalarial Agents

Whole-cell high-throughput screening of the AstraZeneca compound library against the asexual blood stage of Plasmodium falciparum (Pf) led to the identification of amino imidazoles, a robust starting point for initiating a hit-to-lead medicinal chemistry effort. Structure-activity relationship studies followed by pharmacokinetics optimization resulted in the identification of 23 as an attractive lead with good oral bioavailability. Compound 23 was found to be efficacious (ED90 of 28.6 mg·kg-1) in the humanized P. falciparum mouse model of malaria (Pf/SCID model). Representative compounds displayed a moderate to fast killing profile that is comparable to that of chloroquine. This series demonstrates no cross-resistance against a panel of Pf strains with mutations to known antimalarial drugs, thereby suggesting a novel mechanism of action for this chemical class.

Iron-Catalyzed Selective N-Methylation and N-Formylation of Amines with CO2

We herein describe an efficient iron-catalyzed selective N-methylation and N-formylation of amines with CO2 and silane using mono-phosphine as ligand. With commercially available [CpFe(CO)2]2 as catalyst, Fe-catalyzed methylation of amines was achieved with triphenylphosphine as a ligand. Using tributylphosphine as a ligand, Fe-catalyzed formylation of amines was realized at a lower temperature. The method was successfully applied in the late-stage methylation and formylation of drug molecules containing amine moiety. (Figure presented.).

Synthesis of novel styryl-: N -isopropyl-9 H -carbazoles for designing trans -conjugated regular silicon hybrid materials

An efficient synthesis and characterization of several new, conjugated styryl-carbazole compounds functionalized by monovinylsilanes in a stereocontrolled approach is presented. All N-organic derivatives were successfully examined in silylative coupling in the presence of ruthenium-hydride complexes 4 and 5. Furthermore, a novel class of vinylene-arylene linear oligomeric materials with 1,4-bis(dimethylvinylsilyl)naphthalene in the main chain was produced. Both reactions proceed very effectively, stereo- and regioselectively, allowing one to obtain E-isomer derivatives with high isolation yields.
