Benzo[b]thiophen-2-yl-hydrazonoesters 4 were synthesized by coupling of 2-diazo-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide (1) with either ethyl cyanoacetate or ethyl acetoacetate. The reactivity of 4 toward a variety of nitrogen nucleophiles was investigated to yield pyrazole, isoxazole, pyrimidine, triazine, pyrazolopyridine, and pyrazolopyrimidine derivatives. © 2003 Wiley Periodicals, Inc
苯并[b]噻吩-2-基-腙酯4是通过2-重氮-4,5,6,7-四氢苯并[b]噻吩-3-甲酰胺(1)与氰基乙酸乙酯或乙酰乙酸乙酯偶联合成的。研究了 4 对各种含氮亲核试剂的反应性,以产生吡唑、异恶唑、嘧啶、三嗪、吡唑并吡啶和吡唑并嘧啶衍生物。© 2003 Wiley Periodicals, Inc. 15:15–20, 2004; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/.hc10205
