A direct catalytic substitution of various allylic and benzylic alcohols with synthetically useful, but acid-sensitive Boc, Bus, and Dios protected amine nucleophiles, which have not been well utilized for Lewis acid catalysis, with various functionalities (OTBS, OTHP, etc.) was efficiently catalyzed by 1 mol% of Au(III) under mild conditions.
用合成上有用但对酸敏感的Boc,Bus和Dios保护的胺亲核试剂直接催化取代各种烯丙基和苄基醇,这些胺亲核试剂尚未很好地用于路易斯酸催化,具有各种功能(OTBS,OTHP等)。在温和的条件下被1 mol%的Au(III)有效地催化。
