  Synthesis, stereochemistry, and chiroptical spectra of cyclopropyl lactones and thionolactones

  摘要：

  Several optically active substituted 3-oxabicyclo[3.1.0]hexan-2-ones and their thiocarbonyl analogues were synthesized, and their circular dichroism spectra are reported. It was found that the n-pi* Cotton effect sign is determined by the helicity of an inherently chiral chromophore formed by the lactone or thiolactone group and the cyclopropyl moiety. The pi-pi* Cotton effect of thiocarbonyl compounds shows opposite sign to that observed for the lowest energy transition. The crystal structures of two compounds were solved to establish their molecular geometries. Copyright (C) 1996 Elsevier Science Ltd

• Cyclopropane derivatives as potential human serine racemase inhibitors: unveiling novel insights into a difficult target

  D-Serine is the co-agonist of NMDA receptors and binds to the so-called glycine site. D-Serine is synthesized by human serine racemase (SR). Over activation of NMDA receptors is involved in many neurodegenerative diseases and, therefore, the inhibition of SR might represent a novel strategy for the treatment of these pathologies. SR is a very difficult target, with only few compounds so far identified exhibiting weak inhibitory activity. This study was aimed at the identification of novel SR inhibitor by mimicking malonic acid, the best-known SR inhibitor, with a cyclopropane scaffold. We developed, synthesized, and tested a series of cyclopropane dicarboxylic acid derivatives, complementing the synthetic effort with molecular docking. We identified few compounds that bind SR in high micromolar range with a lack of significant correlation between experimental and predicted binding affinities. The thorough analysis of the results can be exploited for the development of more potent SR inhibitors.

  Several optically active substituted 3-azabicyclo[3.1.0]hexan-2-ones and their thiocarbonyl analogues have been synthesized, and their circular dichroism spectra studied. The crystal structure of thiolactam 1a showed that the bicyclic skeleton of the title compounds assumes a sofa-like geometry. It is postulated that the cyclopropyl moiety and amide or thioamide group constitute an inherently chiral chromophore, helicity of which determines the Cotton effect sign corresponding to the n-pi* electronic transition. The weak pi-pi* Cotton effect of thiolactams shows opposite sign to that observed for the lowest energy excitation. (C) 1997 Elsevier Science Ltd.
