  4-(9-Fluorenylmethyloxycarbonyl)phenylhydrazine (FmPH):  A New Chromophoric Reagent for Quantitative Monitoring of Solid-Phase Aldehydes^1-3

  摘要：

  A direct method for quantifying solid-phase aldehydes has been developed, using a new reagent, 4-(9-fluorenylmethyloxycarbonyl)phenylhydrazine (FmPH). The FmPH reagent was synthesized in three steps (24% overall yield) from commercially available p-hydrazinobenzoic acid. Resin-bound aldehydes reacted quantitatively with FmPH, in the presence of trimethylorthoformate (TMOF) as a dehydrating agent, to form a highly conjugated, immobilized FmPH-hydrazone. Next, mild treatment of the hydrazone with an excess of piperidine-N,N-dimethylformamide (1:1) released the piperidine-dibenzofulvene adduct chromophore (epsilon(301nm) = 7800 M-1 cm(-1)) from the support. FmPH quantitation of aldehydes proved to be a straightforward, sensitive, and reproducible technique for monitoring resin-bound aldehydes [albeit insufficiently reactive to allow reliable quantification of ketones]. The FmPH aldehyde assay is applicable to a range of solid supports, as demonstrated specifically for poly(ethylene glycol)-polystyrene (PEG-PS), aminomethylpolystyrene (AMP), and cross-linked ethoxylate acrylate resin (CLEAR).

  One linker, broad application: A simple sulfonamide linker for primary and secondary amines was used for the construction of small libraries of privileged indole and quinolone structures on a solid phase. After the synthesis, the products can be liberated ion a traceless manner under electron transfer conditions or according to a “safety catch” principle.

  一个接头，广泛应用：用于伯胺和仲胺的简单磺酰胺接头用于在固相上构建具有特权吲哚和喹诺酮结构的小型文库。合成后，可以在电子转移条件下或根据“安全捕获”原理以无痕迹的方式释放产物。
