Unrestricted: Pseudoephenamine is introduced as a versatile chiral auxiliary and an alternative to pseudoephedrine in asymmetric synthesis. It is free from regulatory restrictions and leads to remarkable stereocontrol in alkylation reactions, especially in those that form quaternary carbon centers. Amides derived from pseudoephenamine exhibit a high propensity to be crystalline substances, and provide
不受限制:Pseudoephenamine 被引入作为多功能手性助剂和不对称合成中伪麻黄碱的替代品。它不受监管限制,并在烷基化反应中产生显着的立体控制,特别是在那些形成季碳中心的反应中。源自伪苯胺的酰胺表现出高度倾向于成为结晶物质,并在 NMR 光谱中提供清晰、明确的信号。
