Described herein are compounds and pharmaceutical compositions containing such compounds, which modulate the activity of 5-lipoxygenase-activating protein (FLAP). Also described herein are methods of using such FLAP modulators, alone and in combination with other compounds, for treating respiratory, cardiovascular, and other leukotriene-dependent or leukotriene mediated conditions or diseases.

Syntheses of CJ-15,161 (1) involving intermolecular N-arylation of an appropriately functionalized diamine, obtained from the precursor α-amino acids or, more conveniently, from the corresponding 1,2-amino alcohols via 1,2,3-oxathiazolidine-2,2-dioxide 22, are reported.

unactivated α,β-unsaturatedamides is described. Consistently high enantiomeric excesses and yields were obtained over a wide range of alkyl thiol pronucleophiles and electrophiles under mild reaction conditions, enabled by a novel squaramide-based bifunctional iminophosphorane catalyst. Low catalyst loadings (2.0 mol %) were achieved on a decagram scale, demonstrating the scalability of the reaction. Computational
Enantiomerically pure β-hydroxyalkyl and β-aminoalkyl ferrocenyl sulfides have been synthesized in good yields from mercaptoferrocene and amino alcohol derivatives. Primary β-aminoalkyl sulfides allowed the synthesis of tetrahydro-1,4-thiazepines containing the ferrocene moiety with good diastereoselectivity and β-iminoalkyl sulfides. Some of these derivatives have successfully been employed as ligands

A high-yielding synthesis of a phenylglycine derived (E,Z)-dienylboronate en route to the C16-C23 tetraene of the polyene macrolide viridenomycin is described. Crucial to this synthesis was the development of conditions enabling ready access to synthetically useful amino acid derivatives that should be widely applicable to other amino acids. These conditions confer advantages of increased yield and
