オキシムエーテルの不斉還元は文献に記載されているが、ほとんどの場合、これはN−アルコキシアミンを得るためのものではなく、得られる生成物はアミンへと完全に還元されている。これは、通常、キラルな1,2−アミノ−アルコールの存在下において、還元剤としてのボラン錯体を必要とする(J.CHEM.SOC.PERKIN TRANS.I,1985,2039)。オキシムエーテルをN−アルコキシアミンへと不斉還元した最初の例が論文(J.ORG.CHEM.,1997,5385)に記載されており、この論文には、不斉ボランを試薬として使用することが記載されている。これと同年に、同じグループが、この反応の展開(scope)について記載した論文(TETRAHEDRON:ASYMMETRY,1997,497)を発表しており、この論文においては、キラルなアミノアルコールが化学量論量を超える量(1.32当量)で使用されており、このオキシムエーテルは環内にあり、芳香環に直接結合している。後年になって、この種の反応について記載した報告が散見されるようになったが、還元を行うと必ず、完全に還元されたアミンおよびN−アルコキシアミンの混合物となってしまい、N−アルコキシアミンの方が混合物の少量成分となる場合もあった(TETRAHEDRON:ASYMMETRY,2001,2185;TETRAHEDRON:ASYMMETRY,2003,1463;JOURNAL OF FLUORINE CHEMISTRY,2007,34;TETRAHEDRON:ASYMMETRY,2008,788)。これらのグループはいずれもキラルなアミノアルコールを1当量を超える量で使用していた。2008年に、唯一、将来性のある本発見と類似の結果(混合物については述べられていない)、すなわち、芳香環(この場合はヘテロ環)に直接結合しているオキシムエーテルを使用し、不斉源としてキラルなアミノアルコール(1.2当量)を化学量論量を超える量で用いて、オキシムエーテルを不斉還元することにより、高純度の(clean)N−アルコキシアミンが得られることが報告されている(TETRAHEDRON:ASYMMETRY,2008,956)。
