The effective and efficient removal of the BF2 moiety from F-BODIPY derivatives has been achieved using two common Brønsted acids; treatment with trifluoroacetic acid (TFA) or methanolic hydrogen chloride (HCl) followed by work-up with Ambersep® 900 resin (hydroxide form) effects this conversion in near-quantitative yields. Compared to existing methods, these conditions are relatively mild and operationally simple, requiring only reaction at room temperature for six hours (TFA) or overnight (HCl).
已成功实现了从F-BODIPY衍
生物中高效快速地去除
BF2团的方法,使用两种常见的Brønsted酸;用
三氟乙酸(TFA)或
甲醇盐酸(HCl)处理,然后用Ambersep® 900
树脂(氢氧化物形式)处理,可在接近定量产率下完成这种转化。与现有方法相比,这些条件相对温和且操作简单,只需在室温下反应六小时(TFA)或过夜(HCl)。
