Despite the widespread theranostic utilization of cyanine dyes (Cy7), their synthetic method is still limited with pyridine or cyclohexanone derivatives as starting materials. Herein, we report the synthesis of Cy7 from furfural derivatives. First, a one-pot reaction strategy is developed to solve the unstable problem of the Stenhouse salts. Second, a stepwise condensation strategy is exploited to
尽管花青染料 (Cy7) 被广泛用于治疗诊断,但它们的合成方法仍然受限于以吡啶或环己酮衍生物为起始原料。在此,我们报道了从糠醛衍生物合成 Cy7。首先,开发了一种一锅法反应策略来解决 Stenhouse 盐的不稳定问题。其次,利用逐步缩合策略区域选择性地合成不对称的 Cy7。该方法具有操作简单、产率高、底物适用范围广、官能团耐受性好等优点。
