mixture of colored products. The three major conversion end-products, of which two are inhibitors of protein tyrosine phos-phatases (PTPs), were isolated by chromatographic methods and their structures characterized by spectro-scopic analysis, including NMR and MS combined with computer assisted structure elucidation, and, finally, confirmed by independent chemical synthesis.

在DMSO溶液中,将2-氨基-4 H-噻唑并[5,4- b ]吲哚转化为有色产物的复杂混合物。通过色谱法分离了三种主要的转化终产物,其中两种是蛋白酪氨酸磷酸酶(PTP)抑制剂,其结构通过光谱分析进行了表征,包括NMR和MS结合计算机辅助的结构解析,以及最后,通过独立的化学合成证实。描述了由氨基吲哚或2-溴-1-(2-硝基-苯基)乙酮制备的2-氨基-4 H-噻唑并[5,4- b ]吲哚及其N-乙酰基衍生物的合成。
