Bridged bicyclic compounds and their derivatives as neuroprotective agents and methods of use thereof
Neuroprotective compounds for reducing neurological damage due to cellular stress in an individual are of Formula 1: ##STR00001##
or an enantiomer, diastereomer, racemic mixture or a pharmaceutically acceptable salt thereof, wherein: Ar=aryl; Y=aryl substituent (ortho, meta, or para) selected from the group consisting of: alkyl, alkyloxy, alkylamino, R.sup.5R.sup.6N, and halo; XO, N, or S; RH, alkyl, aryl, OH, alkyloxy, aryloxy, NH.sub.2, alkylamino, R.sup.5R.sup.6N, or arylamino; R.sup.1 and R.sup.2=alkylcarbonyl, arylcarbonyl, alkyl, or H, individually; R.sup.3=arylCHCH, alkylCHCH, alkyl; R.sup.4H, alkyl, or aryl; and R.sup.5 and R.sup.6=alkyl, individually. Methods of reducing neurological damage due to cellular stress in an individual include administering to the individual during or after the cellular stress a neuroprotective compound of Formula I in a therapeutically effective amount to restore synaptic function during or after the cellular stress.
SYNTHESIS OF BICYCLO[2.2.2]OCTANE DERIVATIVES
Provided is a process for the preparation of certain 1,4-bicyclo[2.2.2]octane derivatives. The new synthetic procedure involves treating 1,4-dimethylene cyclohexane with an oxidizing agent in the presence of a transition metal catalyst to afford an oxo-substituted bicyclo[2.2.2]octane species. This intermediate structure can then be further derivatized. The processes of this disclosure thus affords a novel and simplified means for the commercial production of a wide variety of bicyclo[2.2.2]octane derivatives.
