Ceria nanoparticles as heterogeneous catalyst for CO2 fixation by omega-aminoalcohols

In contrast to gamma-Al2O3, TiO2, ZrO2, MgO and Y2O3, CeO2 is a reusable catalyst for the reaction of CO2 with omega-aminoalcohols to form cyclic carbamates; the highest yield (68%) was obtained for the preparation of N-alkyl 1,3-oxazolidin-2-ones from N-alkyl ethanolamines.

The Synthesis and Configurational Stability of Differentially Protected beta-Hydroxy-beta-amino Aldehydes

Syntheses of 1,1-dimethylethyl (S)-4-formyl-2,2-dimethyl-3-oxazolidinecarboxylate (5) and 1,1-dimethylethyl (4S-trans)-4-formyl-2,2,5-trimethyl-3-oxazolidinecarboxylate (6) from commercially available serine and threonine derivatives are described.The method involves selective reduction of the corresponding oxazolidine esters 3 and 4 using diisobutylaluminum hydride at low temperature.These differentially protected beta-hydroxy-alpha-amino aldehydes are also shown to be produced in 93-95 percent enantiomeric excess (via NMR and HPLC analysis of the Mosher esterderivatives 8 and epi-8)-thus making them useful as chiral, nonracemic synthons for asymmetric synthesis.

Synthesis of Nontoxic Fluorous Sphingolipids as Molecular Probes of Exogenous Metabolic Studies for Rapid Enrichment by Fluorous Solid Phase Extraction

Fluorous solid-phase extraction (FSPE) is a useful technique for efficient selective enrichment of fluorous compounds from nonfluorous molecules. Sphingolipids and their metabolites, which are ubiquitous building blocks of eukaryotic and prokaryotic cell membranes, play crucial roles, for example, as signaling molecules. However, details of the functions and metabolic mechanisms of exogenous sphingolipids have remained unknown compared with those of their endogenous analogs. To better understand these unknown roles, chemical probes with appropriate biological and physicochemical properties are needed. In this study, we designed and synthesized new fluorous sphingolipids to reveal these roles. Furthermore, we confirmed that they could be efficiently and rapidly separated from normal sphingolipids by FSPE, and that they hardly showed any cytotoxic activity, similarly to normal sphingolipids at the same dose. We also showed that these fluorinated ceramides could act as metabolic substrates for sphingomyelin synthase 2 (SMS2). This demonstrates their potential for further biological studies.

SELECTIVE INHIBITORS FOR CYCLIN-DEPENDENT KINASES

This invention provides a class of compounds which are useful for specifically inhibiting cyclin-dependent kinases. This class of compounds finds use in treating diseases resulting from inappropriate activity of cyclin-dependent kinases, including cancer, viral infections (e.g., HIV) neurodegenerative disorders (e.g. Alzheimer’s disease), and cardiovascular disorders (e.g. atherosclerosis). Moreover, certain members of this class are particularly useful for inhibiting cyclin-dependent kinase 7 and are especially useful for the treatment of breast cancer.

A ring-closing metathesis-based approach to the synthesis of (+)-tetrabenazine

A modular stereoselective synthesis of the vesicular monoamine transport inhibitors (+)-tetrabenazine ((+)-1) and (+)-alpha-dihydrotetrabenazine ((+)-2) has been developed. The approach is based on amine 4 and acid 5 as the key building blocks, which were elaborated into macrolactam 3 by amide coupling and a subsequent highly E-selective RCM reaction. Macrolactam 3 could be converted into tetrabenazine in three known steps.

Dirhodium(II) tetrakis(carboxamidates) with chiral ligands. Structure and selectivity in catalytic metal-carbene transformations

Structure-selectivity comparisons are made between chiral dirhodium(II) tetrakis(methyl 2-oxopyrrolidine5-carboxylates), Rh2(5S-MEPY)4 and Rh2(5R-MEPY)4 (5), and dirhodium(II) tetrakis(4-benzyl-2- oxazolidinones), Rh2(4R-BNOX)4 and Rh2(4S-BNOX)4 (6), to ascertain and understand their relative effectiveness as catalysts for enantiocontrol in metal-carbene transformations. The syntheses, spectral characteristics, and X-ray structures for these dirhodium(II) compounds are reported. Each possesses two oxygen- and two nitrogen-donor atoms bound to each . octahedral rhodium with a cis orientation of the nitrogen ligands. The Rh2(MEPY)4 catalysts are significantly more effective than those of Rh2(BNOX)4 in providing a high level of enantiocontrol in intermolecular and intramolecular cyclopropanation reactions, in intermolecular cyclopropenation reactions, and in intramolecular C-H insertion reactions of diazoacetates and diazoacetamides, often reaching >90% enantiomeric excesses. Molecular mechanics calculations that were able to reproduce the X-ray structures of Rh2(5S-MEPY)4 and Rh2(4R-BNOX)4 have been employed to obtain the preferred conformation of the intermediate metal-carbene, but the absolute configurations of cyclopropanation products are opposite to those predicted from the preferred metal-carbene conformation. However, conformational energy minima of the styrene-carbene complex predict the observed enantiomer preference.
