Adjuvants are added to vaccines to enhance the immune response and provide increased protection against disease. In the last decade, hundreds of synthetic immune adjuvants have been created, but many induce undesirable levels of proinflammatory cytokines including TNF-α and IL-6. Here we present smallmolecule NF-κB inhibitors that can be used in combination with an immune adjuvant to both decrease
The First General and Selective Palladium(II)-Catalyzed Alkoxycarbonylation of Arylboronates: Interplay among Benzoquinone-Ligated Palladium(0) Complex, Organoboron, and Alcohol Solvent

Methoxycarbonylation of aryl- and alkenylboron compounds was performed using the palladium(II) acetate/triphenylphosphine [Pd(OAc)2/PPh3] catalyst with p-benzoquinone as a stoichiometric oxidant in methanol at ambient temperature to obtain the corresponding methyl esters in good yields. A wide variety of functional groups including various carbonyl functionalities, nitrile, nitro, sulfone, and unprotected

A synthetic strategy based on tandem application of double Claisenrearrangement and two-directional ring-closingmetathesis reaction as key-steps has been developed for the synthesis of various hitherto unknown tri-, tetra- and pentacyclic benzofused bisoxepin and bisoxocin derivatives.

Phosphoramidite ligands, based on ortho-substituted biphenols and a chiral amine, induce high enantioselectivities (ee's up to 99%) in the copper-catalyzed conjugateaddition of dialkylzinc reagents to a variety of Michael acceptors. Particularly, the best reported ee's were obtained for acyclic nitroolefins.

analogous to crownethers, are described. The chirality of these systems is based, in one case, upon the plane of chirality of paracyclophane systems and, in the other two cases, upon the axis of chirality of bridged biphenyls. Two methods are described for the measurement of chiral selectivity in the formation of complexesbetween these chiral macrocyclic host molecules and chiral guest primary alkylammonium
