  A new series of 3-, 8-substituted pyrazolo[5,1-c][1,2,4]benzotriazine 4-oxides 3 were synthesized and their benzodiazepine receptor (BZR) affinities were evaluated in vitro in comparison with their 5-oxide isomers 2. The 4-oxide compounds 3c,m,n,o showed a better receptor affinity than their corresponding 5-oxide isomers, with an efficacy trend of antagonist/partial inverse agonist. From a structure-affinity relationship point of view some insight in the role played by N-4 and Id-oxide is gained. (C) Elsevier, Paris.
• Stille Coupling Reactions in the Synthesis of Hypoxia-Selective 3-Alkyl-1,2,4-Benzotriazine 1,4-Dioxide Anticancer Agents
  作者：Karin Pchalek、Michael P. Hay

  日期：2006.8.1

  The introduction of a 3-alkyl substituent is a key step in the synthesis of 1,2,4-benzotriazine 1,4-dioxide hypoxia-selective anticancer agents, such as SN29751. The Stille reaction of 3-chloro-1,2,4-benzotriazine 1-oxides ( BTOs) 5 was inhibited by the presence of electron donating substituents on the benzo ring, thus limiting the range of compounds available for SAR studies. The use of 3-iodo-BTOs 8 did not provide a significant improvement in the yields of 3-ethyl-BTOs 6. Microwave-assisted Stille coupling of chlorides 5 gave dramatically improved yields, which were consistently superior to those from the corresponding iodides 8. The application of microwave-assisted synthesis extended the range of substituted BTOs available for SAR studies and provided an efficient, scalable synthesis of the investigational anticancer agent, SN29751 ( 1).
