Two new reactions have been exploited to modify piperidine scaffolds containing the chiral, non-racemic N-(cyanomethyl)oxazolidine system. A Raney nickel mediated decyanation was studied first, followed by an oxidative process using potassium permanganate to furnish enantiopure lactams including oxopipecolic acid derivatives.

已利用两种新反应来修饰含有手性、非外消旋 N-(氰甲基)恶唑烷系统的哌啶支架。首先研究了雷尼镍介导的脱氰作用,然后是使用高锰酸钾的氧化过程,以提供对映体纯内酰胺,包括氧代哌啶酸衍生物。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
