Palladium ureaka! Urea palladacycles are introduced to activate alkylidene malonates for nucleophilic attack. The strategic incorporation of palladium on a urea scaffold give rise to urea catalysts with enhanced reactivity when compared to conventional urea and thiourea catalysts. A variety of alkylidene malonates are easily activated with urea palladacycle catalysts giving rise to the corresponding products in high yield (see scheme). Copyright

New chiral derivatizing agents have been prepared through a simple, short-step synthesis. The absolute configuration of alpha-chiral carboxylic acids can be assigned on the basis of the NMR chemical shift difference between diastereomeric esters. Because of the modular structures of the agents, the anisotropic effect could be easily manipulated to afford large chemical shift differences even in polar solvents.

A straightforward procedure for the synthesis of enantiopure polysubstituted piperidines is reported. It involves the direct generation of chiral non-racemic oxazolo[3,2-a]piperidone lactams that already incorporate carbon substituents on the heterocyclic ring and the subsequent removal of the chiral auxiliary. The key step is a cyclocondensation reaction of (R)-phenylglycinol or other amino alcohols with racemic or prochiral delta-oxo (di)acid derivatives in highly stereoselective processes involving dynamic kinetic resolution and/or desymmetrization of diastereotopic or enantiotopic ester groups.

A series of chiral bifunctional squaramide multiple H-bond donor organocatalysts have been designed and synthesized by the rational assembly of chiral privileged scaffolds of indanol and cinchona alkaloids. In the presence of 1 mol % 1a, the asymmetric Michael addition reaction of 1,3-dicarbonyl compounds to nitroolefins proceeded to provide the product in high yields (up to 92%) and with good to high ee values (up to 96%). The additional H-bond in this squaramide system plays a crucial role in enhancing the enantioselectivity.

A series of inhibitors of the malarial aspartic proteases Plm I and II have been synthesized with L-mannitol as precursor. These inhibitors are characterized by either a diacylhydrazine or a five-membered oxadiazole ring replacing backbone amide functionalities. Molecular dynamics simulations were applied in the design process. The computationally predicted Plm II K i values were generally in excellent agreement with the biological results. The diacylhydrazine was found to be superior over the oxadiazole as an amide bond replacement in the Plm I and II inhibitors studied. An extensive flexibility of the S2? pocket was captured by the simulations predicting the binding mode of the unsymmetrical inhibitors. Plm I and II inhibitors with single digit nanomolar Ki values devoid of inhibitory activity toward human Cat D were identified. One compound, lacking amide bonds, was found to be Plm IV selective and very potent, with a Ki value of 35 nM.

A library of catalysts was designed for asymmetric-hydrogen transfer to acetophenone. At first, the whole library was submitted to evaluation using high-throughput experiments (HTE). The catalysts were listed in ascending order, with respect to their performance, and best catalysts were identified. In the second step, various simulated evolution experiments, based on a genetic algorithm, were applied to this library. A small part of the library, called the mother generation (GO), thus evolved from generation to generation. The goal was to use our collection of HTE data to adjust the parameters of the genetic algorithm, in order to obtain a maximum of the best catalysts within a minimal number of gen-erations. It was namely found that simulated evolution’s results depended on the selection of GO and that a random GO should be preferred. We also demonstrated that it was possible to get 5 to 6 of the ten best catalysts while investigating only 10% of the library. Moreover, we developed a double algorithm making this result still achievable if the evolution started with one of the worst GO.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons.

A systematic investigation was undertaken to determine the role of the P1′ sidechain in a series of hydroxyethylene isostere based inhibitors of HIV-1 protease. Substitution and homologation of the benzyl P1′ side chain of the Phe-Phe isostere based pseudo peptides 1 (L-682,679) and 2 (L-685,434) with various heteroalkyl groups leads to a series of extremely potent inhibitors of the enzyme. Several examples of the most potent inhibitors were very effective in an ex vivo cell based viral spread assay using human H9 T- lymphocytes and the IIIb isolate of HIV-1. Compound 19 is 120 times more potent than 1 and 16 times more potent than 2 in inhibiting the spread of infection in this assay.
