    摘要: A novel three-step process for resolving a racemic spiro-hydantoin compound into its optical antipodes is disclosed, which involves (1) reacting said racemic compound with an optically-active asymmetric isocyanate of the formula RNCO, wherein R is (S)- or (R)-1-phenylethyl or (S)-or (R)-1-(1-naphthyl)ethyl, to form the corresponding diastereomeric ureido compound; (2) separating the resulting diastereomeric mixture into its component parts, and (3) thereafter converting the separated ureido diasteromers obtained in step (b) to the corresponding asymmetric hydantoin compounds by treatment with an alkali metal lower alkoxide (C.sub.1 -C.sub.4), followed by acidification, whereupon the desired optical isomer is obtained. The final products so obtained, such as (4S)-(+)-6-fluoro-2,3-dihydro-spiro-[4H-1-benzopyran-4,4'-imidazolidine]-2',5'-dione(sorbinil) and (5'S)-3'-chloro-5', 6',7',8'-tetrahydro-spiro[imidazolidine-4,5'-quinoline]-2,5-dione, are known to be useful in preventing or alleviating certain chronic diabetic complications. The aforementioned diastereomeric ureido intermediates are novel compounds.

    摘要: Certain substituted 1-phenyl-3-(aminoalkylidene)-2(1H,3H)-indolones are highly potent gabaergic agents, valuable in the treatment of individuals suffering from schizophrenia or reversing the side effects of a previously or concurrently administered neuroleptic agent; or in the treatment of epilepsy. A wider class of substituted 1-phenyl-3-(aminoalkylidene)-2(1H,3H)-indolones, together with 1-phenyl-3-(2-pyrrolidinylidene)-2(1H,3H)-indolones, and homologs thereof, are valuable in the treatment of anxiety.
