Page/Page column 61-62, (2012/05/19)
The present invention relates to compounds and compositions useful as antioxidants and in particular to selenium containing compounds of formula (I): wherein n is 1, 2, or 3; m is 2, 3, 4, or 5; and each R] is independently -(optionally substituted C 1 -C3 alkylene) p-OH, where p is 0 or 1, or a salt thereof. The invention also relates to the use of these seleno-compounds in the treatment of diseases or conditions associated with increased levels of oxidants produced by myeloperoxidase (MPO), such as for instance, atherosclerosis.

The combination of catalytic amounts of p-toluenesulfonic acid and 1 equiv of N-halosuccinimide afforded highly selective ring-halogenation of N-acetyl-l-tyrosine, furnishing either N-acetyl-3-halo-l-tyrosine analogues or mixed 3,5-dihalo derivatives in a one-pot reaction with excellent yields at room temperature.
