摘要:
A process for preparing an R enantiomer of a compound of the formula (I): ##STR1## wherein Ar is 3-methoxyphenyl, 3-chlorophenyl, or 1-naphthyl, and X is independently selected from the group consisting of H, F, Cl, Br, I, phenyl, CF.sub.3, CF.sub.2 H, CFH.sub.2, lower alkyl (e.g., Me), O-lower alkyl (e.g., OMe), OCH.sub.2 CF.sub.3, OH, CN, NO.sub.2, C(O)-lower alkyl (e.g., C(O)Me), C(O)O-lower alkyl (e.g., C(O)OMe), C(O)NH-lower alkyl (e.g., C(O)NH--Me), C(O)N-lower alkyl.sub.2 (e.g., C(O)NMe.sub.2), OC(O)-lower alkyl (e.g., OC(O)Me), and NH--C(O)-lower alkyl (e.g., NH--C(O)Me), where "lower alkyl" is selected from a group consisting of 1 to 6 carbon atoms, and m is an integer between 1 and 5, by asymmetrically and enantioselectively reducing an imine with a reducing agent/chiral auxiliary agent complex so as to produce an enantiomeric excess of R enantiomer of the compound of formula (I) over the S enantiomer of the compound of formula (I). The process is especially useful to produce compounds (R)-(+)-N-[1-(3-methoxyphenyl)ethyl]-3-(2-chlorophenyl)propanamine and (R)-(+)-N-[1-(3-methoxyphenyl)ethyl]-3-(phenyl)propanamine. Enantiomeric excess of the R enantiomer over S enantiomer of greater than 65% have been achieved.

Method and compositions for treating a patient having a neurological disease or disorder, such as stroke, head trauma, spinal cord injury, spinal cord ischemia, ischemia- or hypoxia-induced nerve cell damage, epilepsy, anxiety, neuropsychiatric or cognitive deficits due to ischemia or hypoxia such as those that frequently occur as a consequence of cardiac surgery under cardiopulmonary bypass, or neurodegenerative diseases such as Alzheimer's Disease, Huntington's Disease, Parkinson's Disease, or amyotrophic lateral sclerosis (ALS).
摘要:
The present invention features calcilytic compounds. “Calcilytic compounds” refer to compounds able to inhibit calcium receptor activity. Also described are the use of calcilytic compounds to inhibit calcium receptor activity and/or achieve a beneficial effect in a patient; and techniques which can be used to obtain additional calcilytic compounds.
