• Highly Diastereo‐ and Enantioselective Synthesis of Nitrile‐Substituted Cyclopropanes by Myoglobin‐Mediated Carbene Transfer Catalysis
  作者：Ajay L. Chandgude、Rudi Fasan

  DOI：10.1002/anie.201810059

  日期：2018.11.26

  chemobiocatalytic strategy for the highly stereoselective synthesis of nitrile‐substituted cyclopropanes is reported. The present approach relies on an asymmetric olefin cyclopropanation reaction catalyzed by an engineered myoglobin in the presence of ex situ generated diazoacetonitrile within a compartmentalized reaction system. This method enabled the efficient transformation of a broad range of olefin substrates

  报道了用于腈立体取代的环丙烷的高度立体选择性合成的化学生物催化策略。本方法依赖于在隔室反应系统中在异位产生的重氮乙腈存在下，由工程化的肌红蛋白催化的不对称烯烃环丙烷化反应。该方法能够以高达99.9％的de和ee以及高达5600的营业额高效地以制备规模有效地转化各种烯烃底物。可以进一步精制酶促产物以提供各种官能化的手性环丙烷。这项工作扩大了可通过生物催化获得的具有合成价值的非生物转化的范围，并为在生物催化卡宾转移反应中实际和安全地利用重氮乙腈铺平了道路。

  日期：2019.6.24

  porphyrin catalyzed regioselective transfer hydrogenolysis of both activated and unactivated cyclopropanes employing iPrOH as the hydrogen source was discovered. The reaction mechanism for the C–C σ-bond activation of cyclopropanes was identified through an initial radical substitution with rhodium(II) metalloporphyrin radical to give a rhodium porphyrin alkyl, followed by hydrogenolysis with iPrOH to give

  α-Arylations of cyclopropyl and related nitriles provide access to important synthetic intermediates and pharmacophores for biologically active molecules. However, robust methods for coupling of sterically encumbered partners have remained elusive. Through optimization using high-throughput experimentation (HTE), the NiXantphos ligand was found to be effective in the coupling of sterically hindered

  the cells were strongly determined by the nature of the halogen substituent. The synthetic utility of the biocatalytic process was illustrated by an efficient and multi-gram scale biotransformation and synthesis of enantiopure 2,2-dichloro-3-phenylcyclopropanecarboxylic acid and amide in both enantiomeric forms.
