  Asymmetric Total Synthesis of Neoxaline

  摘要：

  A first asymmetric total synthesis and determination of the absolute configuration of neoxaline has been accomplished through the highly stereoselective introduction of a reverse prenyl group to create a quaternary carbon stereocenter using (-)-3a-hydroxyfuroindoline as a building block, construction of the indoline spiroaminal via cautious stepwise oxidations with cyclizations from the indoline, assembly of (Z)-dehydrohistidine, and photoisomerization of unnatural (Z)-neoxaline to the natural (E)-neoxaline as the key steps.

  日期：2017.4

  The oxidation of roquefortine C to the nitrone roquefortine L was investigated using a number of different electrophilic oxidizing reagents. mCPBA and Oxone were shown to be the most effective in achieving this transformation, while unfavorable steric interactions precluded oxidation by bulky reagents such as Davis oxaziridine. Finally, each of the oxidants was shown to promote aromatic hydroxylation
