title: The absolute configuration of SU 23397: a novel neuroleptic agent.
abstract: The absolute configuration of a novel chiral neuroleptic agent SU 23397 (I) was determined by ORD comparison of (+)-5-methoxy dihydro coumarilic acid (VIII), a synthetic precursor of SU 23397 (I), with (+)-dihydro coumarilic acid, whose absolute configuration is known. This assignment was confirmed by oxidative degradation of (+)-5-methoxy dihydro coumarilic acid VIII to D-(+)-malic acid.
