the corresponding amines 9a,b were prepared on large scale in 41–51 and 27–39% overall yield, respectively, starting from N-phenylsulfonyl-protected pyrrole. The target compounds contain the desired functional groups for attachment of biomolecules such as proteins. During synthesis, an unprecedented partial reduction of the pyrrole ring with NaBH3CN in glacial AcOH was observed, for which a plausible
两个新的ω - (1个ħ吡咯-3-基)链烷酸8A,b和相应的胺9A,b被大规模在41-51和27-39%的总收率制备,分别从开始Ñ -苯-保护的吡咯。目标化合物包含用于附着生物分子(例如蛋白质)的所需官能团。在合成过程中,观察到在冰川AcOH中NaBH 3 CN对吡咯环进行了前所未有的部分还原,为此提出了一个合理的机理(方案3)。
