The development of a multigram synthesis of 3-exo-isopropylbicyclo[2.2.1]heptan-2-endo-amine hydrochloride (1) (also known as BRD4780 and AGN-192403) is described. The process involves protection of the amine as 4-nitrobenzyl carbamate, pNZ, which enables chiral SFC chromatography. The absolute configuration (AC) of the individual enantiomers has been determined by Mosher’s amide method, VCD spectroscopy
描述了 3- exo -isopropylbicyclo[2.2.1]heptan-2- endo -amine hydrochloride ( 1 )(也称为 BR
D4780 和 AGN-192403)的多克合成的开发。该过程涉及将胺保护为
氨基甲酸 4-硝基苄酯 pNZ,从而实现手性 SFC 色谱。单个对映体的绝对构型 (AC) 已通过 Mosher 的酰胺法、
VCD 光谱学和 X 射线晶体学确定。我们强调
VCD 方法是一种快速有效的 AC 测定方法,可以直接部署在目标化合物上。
