available phenol, followed by a Newman–Kwart rearrangement. Resolution by preparative chiral HPLC and oxidative cleavage give the targeted Brønsted acid in >99% ee. A convenient route to an original chiral sulfonic acid is disclosed. The synthesis is based on an optimized and regioselective direct bis-orthoarylation of a commercially available phenol, followed by a Newman–Kwart rearrangement. Resolution
摘要 公开了获得原始手性磺酸的简便方法。合成是基于对市售苯酚的优化和区域选择性直接双原位芳构化,然后进行纽曼-科沃特重排。通过制备型手性HPLC拆分和氧化裂解可得到目标99%ee的布朗斯台德酸。 公开了获得原始手性磺酸的简便方法。合成是基于对市售苯酚的优化和区域选择性直接双原位芳构化,然后进行纽曼-科沃特重排。通过制备型手性HPLC拆分和氧化裂解可得到目标99%ee的布朗斯台德酸。
