  Diastereospecific fluorination of substituted azepanes

  摘要：

  Fluorination of bioactive compounds is an important step in drug discovery and development. Fluorination has been extensively studied in acyclic systems, carbocycles, and fused heterocycles. However, there is no report on fluorination of azepanes. As azepanes are components of many biologically active substances and natural products. We herein present the first fluorination examples of substituted azepanes. Fluoroazepanes were prepared by deoxyfluorination diastereospecifically in excellent yields. The absolute configuration at the fluorination site was unambiguously assigned by 2D NMR spectroscopy. (c) 2012 Elsevier Ltd. All rights reserved.

  日期：——

  Substituted azepanes are common bioactive epitopes with flexible ring structures. The conformational effects of monofluorination in model azepane rings were investigated by 1H NMR spectroscopy and computational modelling. A single fluorine atom, installed diastereoselectively, was found to bias the azepane ring to one major conformation for one diastereomer.
