from commercially available reagents to afford the desired product in high enantioselectivity. The reaction was compatible with a free amino group, thus allowing for expeditious access to enantiomerically enriched 1,5‐benzothiazepines, which are important chemical entities in medicinal chemistry.
轻柔地进行:标题反应在质子转移条件下用由市售试剂制备的催化剂进行,以高对映选择性提供所需产物。该反应与一个游离氨基相容,因此可以快速获得对映体富集的1,5-苯并噻嗪类,这是药物化学中的重要化学实体。
