Towards the synthesis of symmetrical and unsymmetrical β,β-diarylacroleins for assembling diarylmethine fragments present in biologically important molecules, we have developed a new Weinreb amide (WA) based buildingblock, derived from propiolic acid. The WA functionality present in this compound allowed the sequential addition of various arylmagnesium bromide reagents in a controlled manner. The
为了合成对称和不对称的 β,β-二芳基丙烯醛以组装存在于生物学重要分子中的二芳基次甲基片段,我们开发了一种新的基于 Weinreb 酰胺 (WA) 的结构单元,它来源于丙炔酸。该化合物中存在的 WA 官能团允许以受控方式顺序添加各种芳基溴化镁试剂。已开发的获取 β,β-二芳基丙烯醛的方法已被用于合成具有生物学意义的 3-芳基烷酮分子。

of the indatraline enantiomers. This CSA was also tested for its ideal molar ratio, temperature, and solvent. Optimized conditions could be achieved that made determination of enantiopurity for (1R,3S)‐indatraline up to 98.9% enantiomeric excess (ee) possible. To quantify even higher enantiopurities, a high‐performanceliquid chromatography (HPLC) method based on a modified β‐cyclodextrine phase was
