Abstract An understanding of the mechanism by which racemization occurs in the Hantzsch reaction preparation of 2-(1-aminoalkyl)thiazoles has enabled the development of a methodology to prevent racemization. N-tBoc-S-dolaphenine (3) is then synthesized using this methodology.
摘要 对在 2-(1-氨基烷基) 噻唑的 Hantzsch 反应制备中发生外消旋化的机制的理解使得开发一种防止外消旋化的方法成为可能。然后使用这种方法合成 N-tBoc-S-dolaphenine (3)。
