3-n-Pentadecylphenol (hydrogenated cardanol) and its derivative 5-n-pentadecyl-2-tert-butylphenol can be nitrated using nitric acid in acetonitrile or methanol to give mono, di or trinitro products. 5-n-Pentadecyl-2-nitrophenol undergoes reductive carbonylation to give a benzoxazole-2-one derivative. An efficient catalytic oxidation reaction in the presence of MeReO3 has also been studied. (c) 2006 Elsevier Ltd. All rights reserved.

The 2-hydroxy-5-nitrobenzyl group is shown to be an effective protecting group for diazenlumdiolates. O-2-(2-Hydroxy-5-nitrobenzyl)-substituted diazeniumdiolates display enhanced thermal stability, but efficiently release nitric oxide (NO) in pH 7.4 aqueous solutions. A lipophilic analogue incorporated into hydrophobic polymers shows NO surface flux rates comparable to that of the natural endothelium. Importantly, these polymer formulations also show significantly enhanced biocompatibility in vivo with use of a porcine implant model.
