  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.

  Discrimination between Enantiomers of Structurally Related Molecules:  Separation of Benzodiazepines by Molecularly Imprinted Polymers

  摘要：

  Molecular imprinting has been used to create synthetic receptor sites for a series of chiral benzodiazepines. A detailed HPLC analysis of binding properties using molecularly imprinted polymers (MIPs) as the stationary phase showed that binding, as measured by chromatographic retention, shows significant dependence on the chiral match or mismatch. In addition, the shape and spatial orientation of functionality of the imprinted binding site is also critical for recognition. Imprinted polymers, therefore, are not only able to discriminate between enantiomers of the imprinted molecule, they also demonstrate an ability to discriminate between a wide range of enantiomers of structurally related molecules that have not been imprinted. The ability of MIPs to discriminate between enantiomers of molecules in favor of the imprinted absolute configuration, even as the structural homology between the enantiomers and the original template decreases, indicates that the synthetic benzodiazepine receptors may serve as crude mimics of the natural receptor.

  Benzodiazepines are privileged scaffolds in medicinal chemistry, but enantiopure examples containing quaternary stereogenic centers are extremely rare. We demonstrate that installation of the di(p-anisyl)methyl (DAM) group at N1 of 1,4-benzodiazepin-2-ones and 1,4-benzodiazepine-2,5-diones derived from enantiopure proteinogenic amino acids allows retentive replacement of the C3-proton via a deprotonation/trapping

  苯二氮卓类药物是药物化学中的特殊支架，但含有四元立体中心的对映体纯的例子极为罕见。我们证明了在源自对映体纯蛋白氨基酸的 1,4-苯二氮卓-2-酮和 1,4-苯二氮卓-2,5-二酮的 N1 处安装二（对茴香基）甲基 (DAM) 基团允许保留替换C3 质子通过去质子化/捕获协议。多种碳和氮亲电子试剂在该反应中发挥良好作用，为相应的季苯二氮卓类化合物提供了出色的对映选择性。一对非对映体 1,4-苯二氮卓-2,5-二酮的去质子化/捕获实验为构象手性在这些对映选择性反应中的关键作用提供了证据。DAM 基团的酸性去除速度快且产率高，并且可以在 N-Boc 吲哚存在下选择性地进行。因此，现在可以完成具有不同 N1 功能的季苯二氮卓类化合物的合成。

  development of a rapid, one-pot synthesis of diazepinones with simple reagents is described. N-Carboxyanhydrides (NCAs) are employed as amino acid building blocks that react with o-ketoanilines sequentially as electrophiles and nucleophiles to form diazepinones with water and carbon dioxide as byproducts. Notably, these reactions enable the coupling of stereodefined amino acid derived NCAs without racemization
