    Enantioselective Synthesis of “Quaternary” 1,4-Benzodiazepin-2-one Scaffolds via Memory of Chirality
    摘要:
    Glycine-derived 1,4-benzodiazepine-2-ones such as diazepam are chiral by virtue of the boat-shaped conformation of the diazepine ring and exist as a racemic mixture of conformational enantiomers. However, the presence of a chiral center at C-3 of the benzodiazepine perturbs this equilibrium and preferentially stabilizes one ring conformer. We report that N-i-Pr 1,4-benzodiazepine-2-ones derived from (S)-Ala and (S)-Phe can be deprotonated and alkylated in 86-99% ee, despite the fact that the original chiral center is destroyed in the deprotonation step. We attribute this highly enantioselective alkylation to the chiral memory of the benzodiazepine ring. This protocol provides easy access to the previously unexplored "quaternary" 1,4-benzodiazepine-2-ones.

  • Memory of chirality trapping of low inversion barrier 1,4-benzodiazepin-2-one enolates
    作者:Paul R. Carlier、Polo C.-H. Lam、Joseph C. DeGuzman、Hongwu Zhao

    We have previously demonstrated that chiral, enantiopure 3-substituted 1,4-benzodiazepin-2-ones undergo retentive deprotonation/trapping at −78 °C, if the N1-substituent is sufficiently large (e.g., i-Pr). Stereocontrol in this reaction is attributed to the formation of an enantiopure, conformationally chiral enolate; at −78 °C a large N1 substituent (e.g., i-Pr) is needed to impart a sufficient barrier
    先前我们已经证明,如果N1-取代基足够大(例如,i -Pr),则手性,对映体纯的3-取代的1,4-苯并二氮杂-2-酮会在-78°C下发生保持性去质子化/捕获。该反应中的立体控制归因于对映纯的,构象性的手性烯醇盐的形成。在-78°C下,需要一个大的N1取代基(例如i- Pr)来赋予烯醇外消旋作用足够的屏障。在本文中,我们报告了在低反型势垒1,4-苯并二氮杂-2-酮具有较小N1取代基的去质子化/烷基化中实现高对映体过量的策略。

    The invention relates to new optically active or racemic 5-phenyl-1,3,4,5-tetrahydro-2H-1,4-benzodiazepin-2-one derivatives of the general formula (I) ##STR1## wherein R.sup.1 stands for hydrogen, halogen, trifluoromethyl or a nitro group; R.sup.2 stands for hydrogen or alkyl having 1 to 6 carbon atoms; R.sup.3 represents a group conventionally attached to the --CH(NH.sub.2)--COOH group of the known optically active or racemic .alpha.-amino-acids, preferably an optionally substituted lower alkyl group; R.sup.4 is hydrogen, chlorocarbonyl or carbamoyl; and X is hydrogen, halogen or trifluoromethyl, with the proviso that if in the racemic compounds R.sup.4 stands for hydrogen R.sup.3 is other than alkyl having 1 to 6 carbon atoms, in which the centers of asymmetry in the 3- and 5-positions have the same absolute configuration, and pharmaceutically acceptable acid addition salts thereof, and a process for their preparation. The new compounds show valuable enzyme inducing activity and can therefore be employed as active ingredients of pharmaceutical compositions, which are also within the scope of the present invention.
