- Enantioselective synthesis of (S)-3-(4-thiazolyl)-2-tert- butoxycarbonylaminopropionic acid: A chiral building block for renin inhibitor
-
(S)-3-(4-Thiazolyl)-2-tert-butoxycarbonylaminopropionic acid (6), an important structural constituent of the renin inhibitor, has been synthesized from (Z)-3-(4-thiazolyl)-2-benzoylaminoprop-2-enoic acid (4b) by enantioselective hydrogenation using the Ru

- Substituted quinoxaline-2-ones as glutamate receptor antagonists
-
A novel series of substituted quinoxaline 2-ones useful as neuroprotective agents are taught. Novel intermediates, processes of preparation, and pharmaceutical compositions containing the compounds are also taught. The compounds are glutamate receptor antagonists and are useful in the treatment of stroke, cerebral ischemia, or cerebral infarction resulting from thromboembolic or hemorrhagic stroke, cerebral vasospasms, hypoglycemia, cardiac arrest, status epilepticus, perinatal asphyxia, anoxia, seizure disorders, pain, Alzheimer's, Parkinson's, and Huntington's Diseases.
