Pseudoephenamine is shown to be a versatile chiral auxiliary for asymmetric synthesis. It is free from regulatory restrictions and exhibits remarkable stereocontrol in alkylation reactions, especially those that form quaternary carbon centers. Amides derived from pseudoephenamine exhibit a high propensity to be crystalline substances and provide sharp, well-defined peaks in NMR spectra.
伪麻黄碱被证明是一种多功能的手性辅助试剂,可用于不对称合成。它不受监管限制,在烷基化反应中表现出显著的立体控制,特别是那些形成季碳原子的反应。由伪麻黄碱衍生的酰胺倾向于形成结晶物质,并在 NMR 谱中提供尖锐、清晰的峰。
