A series of novel 6-(6-alkoxy-2-naphthyl)oxoalkanoates and alkanamides were synthesized as inhibitors of inflammation and 5-lipoxygenase. They were evaluated in vivo for anti-inflammatory activity in the established adjuvent arthritis assay in rats and in vitro as inhibitors of 5-lipoxygenase in rat basophilic leukemia (RBL) cells. N-Hydroxy-N-methyl-6-(6-methoxy-2-naphthyl)-6-oxohexanamide, compound 28, which is representative of the more potent anti-inflammatory / 5-lipoxygenase inhibitors in the series was approximately twice as potent as the standard, ibuprofen in the adjuvent rat and exhibited an IC50 of 0.25 micromolar in the RBL assay.

A one-pot anti-Markovnikov hydroamination of alkenes is reported. The synthesis of primary and secondary amines from unactivated olefins was accomplished in the presence of a variety of functional groups. Hydrozirconation, followed by amination with nitrogen electrophiles, provides exclusive anti-Markovnikov selectivity. Most products are isolated in high yields without the use of column chromatography
