aldehyde 12, the phenolic hydroxy group was converted into the ether 21 terminating in an alkyne function. Oxidation of the aldehyde to the carboxylic acid provided the chemical probe 22 designed for tag-free photoaffinity labeling. In a proof-of-concept study it could be shown that irradiation of the simple ester 23 indeed yields the methanol insertion product 24. A subsequent click reaction with
以二氮丙啶11为关键中间体制备了新型芳香族二氮丙啶苯甲酸22。在芳环甲酰化和醛 12 的甲基醚官能团裂解后,酚羟基转化为醚 21,以炔官能团为末端。醛氧化成羧酸提供了设计用于无标签光亲和标记的化学探针22。在概念验证研究中,可以证明简单酯 23 的辐照确实产生了甲醇插入产物 24。随后与苄基叠氮化物 20 的点击反应导致了三唑 25。通过酯化实现了一个更复杂的例子bafilomycin A1 (27) 与酸 22。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
