合成了几种新的1,1 ′-双(磺酰基)二茂铁衍生物,用于合成磺酰胺连接的生物缀合物。1,1 ′-双磺酰溴二茂铁可由相应的磺酰氯经双磺酰肼中间体制得。由磺酰氯也可合成双(磺酰基-N-羟基苯并三唑)二茂铁,甘氨酸甲酯与磺酰氯反应可得到二茂铁并菲配合物。所有新化合物的结构均经X射线晶体学表征。合成了用于合成磺酰胺连接的生物缀合物的新型1,1 ′-双(磺酰基)二茂铁。1,1 ′-双磺酰溴二茂铁可由相应的磺酰氯经双磺酰肼中间体制得。以磺酰氯为原料合成了双(磺酰基-N-OBt)二茂铁,甘氨酸甲酯与磺酰氯反应得到了二茂铁膦配合物。
Several new 1,1′-bis(sulfonyl)ferrocenes designed for the synthesis of sulfonamide linked biological conjugates have been prepared. 1,1′-Bis(sulfonylbromide)ferrocene can be produced from the corresponding sulfonylchloride via a bis(sulfonylhydrazide) intermediate. Bis(sulfonyl-N-hydroxybenzotriazole)ferrocene can also be synthesized from the sulfonyl chloride, and reaction of glycine methyl ester with the sulfonyl chloride affords a ferrocenophane complex. All new compounds have been structurally characterized by X-ray crystallography.
